Remazol Red

Dyes caused serious environmental pollution and health problem in many ways. Many dyes have toxic effects on aquatic life and also on humans. Liquid-liquid extraction process is one of the alternatives for dye removal from wastewater. Removal of remazol red 3BS from simulated textile wastewater using tetrabutyl ammonium bromide has been studied at room temperature with total operation time of 18 hours. Several parameters have been studied such as pH, diluents, initial dye concentration, extractant concentration and stripping agents toward the extraction process of the dye. The results show only small effects of pH on the extraction percentage. The best diluent for the extraction is dichloromethane with the percentage of 98%. The percentage of extraction is maximum (97%) at 0.07M of TBAB concentration with the distribution ratio of D= 34.65. Salicylic acid in Na2CO3 with the ratio of 1:2 gives the highest percentage of stripping process. It shows a good performance for liquid-liquid extraction of remazol red 3BS for both removal and recovery processes.

Air sisa buangan tekstil yang mengandungi pewarna adalah merbahaya kepada persekitaran dan mempengaruhi kehidupan akuatik. Kepekatan pewarna ini mestilah dikurangkan ke paras yang dibenarkan sebelum dibuang ke persekitaran. Dalam kajian ini, kaedah pengekstrakan cecair telah digunakan untuk mengkaji perolehan semula pewarna Remazol Brilliant Orange 3R daripada air sisa dengan menggunakan tetrabutilammonia bromida dalam diklorometana. Parameter yang dikaji adalah kesan pelarut, pH larutan, kepekatan pengekstrak, kepekatan awal pewarna dan egen pelucut yang sesuai untuk mengekstrak semula pewarna daripada fasa organik. Keputusan eksperimen menunjukkan hampir 100% daripada 100mgL-1 Remazol Brilliant Oren 3R telah diekstrak menggunakan 0.01 M tetrabutilammonia bromida (TBAB) dan tiada pengaruh pH larutan suapan yang ketara ke atas proses pengekstrakan pewarna. Pewarna yang telah diekstrak boleh diperolehi semula daripada larutan organik dengan menggunakan asid salisilik dalam larutan natrium hidroksida dengan nisbah 1:1. Kata kunci: Pengekstrakan cecair; pewarna reaktif azo; oren 3R; tetrabutilammonia bromida; air sisa tektil Textile wastewater containing dyes is dangerous to the environment and affect mainly to some aquatic life. Their concentration must be reduced to acceptable levels before discharging into environment. In this research liquid-liquid extraction method is used to study on the recovery of Remazol Brilliant Orange 3R dye (orange 3R) from textile wastewater by using tetrabutyl ammonium bromide in dichloromethane. The parameter examined in this research were the effect of diluents, effect of pH, effect of extractant concentration, initial dye concentration and the suitable stripping agent to extract back the dye from organic phase.

A study has been carried out on Ta and Nb recovery by a liquid-liquid extraction process using 4-methylacetophenone (4-MAcPh) as the organic phase. The 4-MAcPh was compared to methyl isobutyl ketone (MIBK) with respect to extraction efficiencies (D values) at different concentrations of H2SO4 in the aqueous phase. The results showed a similar extraction of Nb for both solvents. However, for Ta, extraction efficiency is increased by a factor of 1.3 for 4-MAcPh. In addition, the MIBK solubilized completely after 6 mol∙L−1 of H2SO4 against only a loss of 0.14–4% for 4-MAcPh between 6 and 9 mol∙L−1 of H2SO4. The potential of 4-MAcPh has also been studied to selectively recover Ta from a model capacitor waste solution. The results showed a selectivity for Ta in the presence of impurities such as Ag, Fe, Ni and Mn. The 4-MAcPh also presents the advantage of having physicochemical properties adapted to its use in liquid-liquid extraction technologies such as mixer-settlers.

Abstract Pesticide pollution is a serious problem being faced. Harmful levels of pesticides are found in the water which is used for daily purposes. In the event of such a scenario, this paper presents a working solution for bringing down the Pesticide levels in the water to safe levels by using the method of liquid-liquid extraction. The experimental liquid-liquid equilibrium data on pesticide-water-solvent ternary mixtures at a temperature of 288.15 K are presented here. The pesticide used here is a chlorinated hydrocarbon called lindane found in the water (underground, land), beverages and foods. The solvents used are Petro-ether-Chloroform (1:1), Ethylene di chloride and n-hexane. The equilibrium generation diagram, triangular diagram, tie lines and bimodal curves as well as the distribution coefficient have been determined and reported. The petro-ether-chloroform was found to be the right solvent for the separation of lindane from wastewater because of high selectivity (25.36) and distribution coefficient (4). The extraction process is simulated into ‘C’ language

The distribution equilibrium of gallium(III) between n-octylaniline dissolved in toluene and acidic aqueous succinate media has been investigated as a function of the concentration of extractant in the organic phase and concentration of hydrogen ions and gallium( III) ions in the aqueous phase. The stoichiometry of the extracted species was determined on the basis of slope analysis.Gallium(III) is extracted by the anion exchange mechanism as [RNH3+Ga(succinate)2]org. The temperature dependence of the extraction equilibria was examined by the temperature variation method. The extraction process is favoured with increasing temperature. It was found that a large number of cations and anions have a high tolerance limit. The selectivity of the extraction is increased by the use of suitable masking agents. The method affords the binary separation of gallium(III) from associated elements and was further extended to the analysis of a synthetic mixture.

A highly efficient sulfonylation of para-quinone methides with sulfonyl hydrazines in water has been developed on the basis of the mode involving a tetrabutyl ammonium bromide (TBAB)-promoted sulfa-1,6-conjugated addition pathway. This reaction provides a green and sustainable method to synthesize various unsymmetrical diarylmethyl sulfones, showing good functional group tolerance, scalability, and regioselectivity. Further transformation of the resulting diarylmethyl sulfones provides an efficient route to some functionalized molecules.

To explore environmentally benign method for preparing TiO2, composite photocatalysts TiO2 immobilized on activated carbon fibers (TiO2/ACF) were prepared in caprolactam tetrabutyl ammonium bromide ionic liquid (CPL-TBAB ILs). The TiO2/ACF composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The effects of different preparation condition were discussed by degradation of methyl orange (MO). The results showed that nanoTiO2 particles of mixed grain phase were well deposited on the activated carbon fiber surface. 96% of MO was removed under optimal preparation conditions.
