Adsorption Isotherms for Removal of Heavy Metal Ions (Copper and Nickel) From Aqueous Solutions In Single And Binary Adsorption Processes

This study deals with the removal of single and binary heavy metals, which cause great problems in terms environment human health, through very low cost, economical easily obtainable materials. The purpose this is to investigate single- uptake Copper (II) Nickel ions onto Sepiolite a thermodynamic perspective. For mono-component systems, initial effluent concentration, mixing speed temperature have been studied as function time determine conditions where adsorbents show deal affinity towards Cu Ni aqueous solutions. Before metal adsorption experiments, Physical properties were identified via Brunauer–Emmett–Teller (BET) analysis. ion studies performed at 20, 25, 30, 35 °C. At equilibrium, sorption data individually shown correlate well non-competitive Langmuir, Freundlich, Temkin, Dubinin-Radushkevich isotherms. Among applied isotherm models, one-component values do fit Langmuir best. simultaneous competitive was assessed by extended Freundlich Both equations complied two-component perfectly. Single- binary-sorption results unclose that effect greater than (II).
