TL;DR: The characterization of modified poZZolan by FTIR, TGA/DTG, BET, and DRUV–vis revealed the effectiveness of grafting of amine functional group on pozzolan structure, and the kinetic adsorption data were better fitted with general order for both dyes while for equilibrium models were better fitting by the Liu isotherm model.
Abstract: Natural pozzolan is an amorphous silicate-based material of volcanic origin. In this work, the natural pozzolan was modified by using 3-aminopropyltriethoxysilane (APTES) as a grafting agent. This material was characterized by pHpzc, N2 adsorption/desorption curves, FTIR, TGA/DTG, DRUV, SEM, and elementary analysis. The functionalized materials were used for the removal of Reactive Black 5 (RB-5) and Brilliant Green 1 (BG-1) dyes from aqueous solutions using batch-contact adsorption. The characterization of modified pozzolan by FTIR, TGA/DTG, BET, and DRUV–vis revealed the effectiveness of grafting of amine functional group on pozzolan structure. The kinetic adsorption data were better fitted with general order for both dyes while for equilibrium models were better fitted by the Liu isotherm model. The maximum sorption capacities Q
max (at 50 °C) obtained with the modified pozzolan were 350.6 and 300.9 mg g−1 for BG-1 and RB-5, at pH 9.0 and 2.0, respectively. The thermodynamic parameters show that the removal of dyes was spontaneous and endothermic. The modified material was also tested for the treatment of simulated dye house effluents showing very high efficiency.

TL;DR: The method was further evaluated by analyzing a total of 34 fish residue monitoring samples, of which eight samples were found to be non-compliant containing low residues of LMG.

TL;DR: Intensive removal of the dyes by biomass immobilized on the washer corresponded to a significant decrease in phytotoxicity and a slight decrease in zootoxicity of the dye solutions.

TL;DR: The potentiality of tannin gel (TG) and amine modified Tannin Gel (ATG) has been found as highly effective, eco-friendly and cheap adsorbents for removal of Brilliant Green (BG) dye as mentioned in this paper.
Abstract: The potentiality of tannin gel (TG) and amine modified tannin gel (ATG) has been found as highly effective, eco-friendly and cheap adsorbents for removal of Brilliant Green (BG) dye. In each case, the most efficient adsorption occured at pH 7 with 88.38% for TG and 94.05% removal for ATG, respectively. The adsorption kinetics for TG was found to follow pseudo-first-order kinetic model along with intraparticle diffusion, and for ATG it was found to follow pseudo-second order kinetic model. The experimental data were found to best fit with langmuir isotherm ( r 2 > 0.99 for both gels) with maximum monolayer adsorption capacity of 8.55 mg/g for TG and 20.41 mg/g for ATG. The negative values of Gibb’s free energy (Δ G °) of both gels indicate the spontaneous nature of the adsorption process.The positive values of Δ H ° with respect to both gels suggest the endothermic adsorption nature along with positive values of entropy changes (Δ S °).
