In this study, adsorbents were produced from sewage sludge via chemical and thermal activation processes. Experiments were carried out in a tubular furnace at the heating rate of 20?C min-1 and temperature of 550 ?C with a nitrogen flow rate of 400 mL min-1 for 1 h. Dye adsorption experiments were performed with Remazol Brilliant Blue R for its several concentrations under batch equilibrium conditions by comparing sewage sludge based adsorbents with raw material and a commercial activated carbon. Maximum adsorption capacities of carbonized sewage sludge (CSWS) and activated sewage sludge (ASWS) were found as 7.413 mg g-1 and 9.376 mg g-1 for 100 mg L-1 dye solution, whereas commercial activated carbon had a capacity of 11.561 mg g-1. Freundlich and Langmuir isotherms were used to explain the adsorption mechanism together with pseudo-first-order and pseudo-second-order kinetic models. Langmuir isotherm, which had adsorption capacities of 34.60 mg g-1 (CSWS) and 72.99 mg g-1 (ASWS), provided better fit to the equilibrium data than that of Freundlich isotherm. Pseudo second-order, model which had adsorption capacities of 7.451 mg g-1 (CSWS) and 9.319 mg g-1 (ASWS), was very favorable to explain the adsorption kinetics of the dye with high regression coefficients.

Remazol Brilliant Blue R

Adsorption technology is one of the efficient and facile method used for wastewater treatment. In this research, coconut shell, an agricultural solid waste was converted into activated carbon via furnace induced and zinc chloride chemical activation techniques. The activated carbon was prepared at activation temperature of 600°C. Anionic dyes, Methyl Orange (MO) and Remazol Brilliant Blue R (RBBR) have been selected due to their harmful effect to the environmental and human. Various effect of parameter such as initial dye concentration, initial pH, adsorbent dosage and agitation speed in batch system were investigated to obtain the optimum condition for both dye adsorption on activated carbon. The optimum dye removal efficiency was around 99% when 5g/L of activated carbon was used. Pseudo-second-order model was the best fitted model with highest correlation compared to other kinetic models. The adsorption behaviour of MO was perfectly presented by the Freundlich model while RBBR was well described by Langmuir model. The maximum adsorption capacity for MO was 59.17mg/g and RBBR was 35.09mg/g. Fourier-transform infrared spectroscopy (FTIR) was utilised to analyse the chemical characteristics of activated carbon before and after adsorption.

The adsorption of remazol brilliant blue R (RBBR) dye on pinang frond based activated carbon (PF-AC) was investigated in a batch process. The effects of initial dye concentration, contact time, solution temperature, and solution pH were evaluated. The adsorption equilibrium and kinetic were found to follow Freundlich isotherm models and pseudo-second-order kinetic model, respectively. The mechanism of the adsorption process was found from the intraparticle diffusion model. Result from adsorption thermodynamic show that interaction for RBBR dye was found to be feasible, nonspontaneous, and endothermic. The results indicated that the PF-AC is very effective for the RBBR adsorption from aqueous solution.

The textile industry stands out for generating effluents with high levels of dyes, which have a high polluting potential. Among these dyes, the Remazol Brilliant Blue R azo dye, is one of the most used for dyeing wool and cotton, being released in excess on these effluents. Intended for the carcinogenic and mutagenic potential of this type of dyes, several researches are developed in search of economical technologies for their removal. An adsorption is a viable technique, since several materials can be used for this purpose. Bovine bone activated carbon, as it is a residue from the livestock industry that is easily obtained, has been studied as an adsorbent material in the removal of dyes. Therefore, the objective of this project was to evaluate the performance of the adsorption kinetics of the Remazol Brilliant Blue R dye from the effluents using bovine bone activated carbon. The experiments were carried out in batches, with solutions concentrations of 20, 50 and 100 ppm, and the mathematical models of pseudo-first order, pseudo-second order and intraparticle diffusion were adjusted to the experimental data. For concentrations of 20 and 50 ppm, the model that best fits was the pseudo-first order, while for the concentration of 100 ppm the pseudo-second order model obtained the best result with R2 of 0.992. The intraparticle diffusion model showed that the higher the concentration of the dye in solution, the greater the thickness of the boundary layer and that the intraparticle diffusion does not control the adsorption process in any of the study criteria.

The potential of agricultural waste materials for the removal of synthetic dye, Phenol Red (PR) and Remazol Brilliant Blue R (RBBR) from aqueous solution was investigated. One of the major pollutants of water pollution, dyes, which not only result in enormous damage to the water body but also impact the organism's health, as it is highly toxic and carcinogenic by nature. Agricultural wastes are sustainable adsorbents since they are availability and low cost, which can also replace the traditional activated carbon. Therefore, this study investigated the removal of PR and RBBR from dye solution by adsorption onto the treated adsorbent. Two best out of ten adsorbents were chosen through a screening process using RBBR as a tested dye. Coconut shells (Cocos nucifera) and ambarella peels (Spondias dulcis) were selected as the main adsorbent of this study since they achieved the highest removal rate compared to others. With the selected adsorbent, the experiment was continued to study the effect of different initial dye concentration, adsorbent dosage, contact time, pH, and particle size on dye adsorption. Results show that different parameters can affect the removal rate and adsorption capacity of adsorbent in a different way. The adsorption of dye from aqueous solution onto adsorbent was evaluated using Fourier transform infrared spectroscopy (FTIR) to investigate the functional groups of adsorbent before and after the adsorption process, and it found that the functional group would affect the effectiveness or removal rate and adsorption capacity of adsorbents. The present study indicates that 99.82% of PR with an adsorption capacity of 1.05 mg/g can be removed by 5-gram ambarella peels. While coconut shells had removed 75.78% of RBBR with an adsorption capacity of 7.96 mg/g for 21 hours. The results proved that these agricultural waste were promising materials as an alternative adsorbent for the removal of dye from aqueous solution.

In the present work, activated carbon was prepared from rubber seed coat by physicochemical activation for the removal of Remazol Brilliant Blue R (RBBR) dye from aqueous solution. The effects of dye initial concentration, contact time, solution temperature and pH on RBBR adsorption onto rubber seed coat based activated carbon (RSCAC) were investigated. The adsorption uptake was found to increase with increase in initial dye concentration and contact time. Change in temperature and pH also played an important role to RBBR adsorption capability. Study showed that rubber seed coat is suitable to be used as activated carbon precursor.
