Remediation of contagious metals from mine-used water using Carica Papaya trunk enhanced charcoal produced with HCl acid
Abstract
Consumptions of contagious metals particularly from mine used water usually result in grievous health diseases and loss of aquatic lives. This research concentrated on elimination of specific contagious metals (Co3+, Fe2+, and Pb2+) from mine used water using Carica Papaya Trunk Enhanced Charcoal produced with HCl (CPTEC – HCl). The contagious metals’ concentrations of the mine used water, predominant functional classes and surface structure of the produced CPTEC-HCl were ascertained utilising some analytical techniques. The adsorption (batches) and desorption experiments applying six parameters were carried out. The suitability of the adsorption facts generated was conducted using adsorption isotherms, kinetics, and thermodynamics through linear and non-linear regressions with two error functions. The contagious metals’ original values were higher than the acceptable requirements. After treatment, CPTEC-HCl eliminated the contagious metals completely (100%) using 0.516 g of the adsorbent with 0.028 mm granule-size at 146.576 rpm, 51.718 minutes, pH of 6.969 at 30 °C. The processes were majorly chemisorptions, largely followed Freundlich, Dubinin-Radushkevich isotherms, Pseudo-second-order kinetic models and highly influenced by the adsorption parameters. The adsorption processes were favourable, feasible, and natural. CPTECHCl is an excellent alternative adsorbent for commercial enhanced charcoal in contagious metals’ elimination from real-world effluent especially mined used water.
