Potato peel powder (PP) was prepared from kitchen wastes and explored in removal of Acid Red 73 (AR 73) dye leather dyeing effluent. PP characterized through FTIR, BET, SEM, XRD EDX analysis. SEM micrographs illustrated rough porous structure that support the adsorption process. FTIR spectrum exhibited changes caused by formation hydrogen bonding, complex or other electrostatic interaction after adsorption. Wide frail peaks image indicated existence amorphous carbon. BET analysis mesoporous with average pore diameter 85.98 Å. The impact various influences viz. pH, dosages, concentration, time temperature were batch investigation. maximum AR73 capacity 258.39 mg/g. on complied both Langmuir (R2 = 0.989) Freundlich 0.993) isotherm, preferably model. pseudo-second-order kinetic model 0.999) fitted better, i.e. chemisorption. equilibrium 135.34 ± 1.59 mg/g at 298 K, which decreased to 125.34 1.81, 114.27 1.43, 104.08 1.53 308, 318 328 respectively.

Paper mills inevitably produce various pollutants, including chlorolignin, chlorophenols, chloroguaiacol, furan, cyanide, and heavy metals. These pollutants cause significant threats to aquatic terrestrial life. The pulp paper industries are looking for eco-friendly solutions the disposal of effluents during processing. Moreover, environmental management practices a key concern that may be addressed by removing these using suitable bioremediation techniques. Therefore, we have discussed several nanotechnology based sustainable technologies like use nanoparticles, nanomaterials, nanocomposites, nanoadsorbents, advanced methods such as electrocoagulation photocatalysis, which utilized elimination hazardous from industry effluents. This review finally includes critical insight into potential above-mentioned interventions mitigation contaminants industry. Nevertheless, there few limitations challenges toward implementation technologies, also in this review.
