Acid Blue

Over the years, polyaniline (PANI) has received enormous attention due to its unique properties. Herein, it was chosen to develop a new polymeric composite material: reduced graphene oxide/polyaniline (rGO/PANI). The composite was prepared by a simple and cost-effective fabrication method of formation by mixing and sonication in various conditions. The obtained materials were characterized and identified using various techniques such as scanning electron microscopy (SEM), Raman and ATR–FTIR spectroscopy, and X-ray diffraction (XRD). The objective of the paper was to confirm its applicability for the removal of contaminants from water. Water could be contaminated by various types of pollutants, e.g., inorganics, heavy metals, and many other industrial compounds, including dyes. We confirmed that the Acid Blue 129 dyes can be substantially removed through adsorption on prepared rGO/PANI. The adsorption kinetic data were modeled using the pseudo-first-order and pseudo-second-order models and the adsorption isotherm model was identified.

The Relationship

A technique is proposed for obtaining electroconductive, mechanically strong, and elastic composite material based on polypyrrole and hydrophilized polyethylene. The relationship is established between the process parameters and properties of the composite material such as electroconductivity and mechanical strength. Several methods are considered in the view of increasing electroconductivity of the material. Physical and mechanical properties of the composite material are investigated.

Shell Powder

The present study investigates the potential of Simarouba glauca seed shell powder as a cost-effective adsorbent for the removal of the cationic dyes Malachite green (MG), Methylene blue (MB) and Rhodamine B (RB) from aqueous solutions. The adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD), as well as by Brunauer–Emmett–Teller (BET) and elemental (CHNS) analyses. Batch mode adsorption studies were carried out varying the experimental conditions, such as initial dye concentration and contact time, adsorbent dose, pH and particle size, in order to assess the adsorbent capacity for the removal of cationic dyes from wastewater. The experimental data were analysed using the Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherms. The data fitted well the Langmuir model for the dyes studied. Kinetic data were analysed using the pseudo-first order, pseudo-second order, intraparticle diffusion and Boyd models. The experimental results showed that the pseudo-second order model fitted well.
