摘要: Using the Taguchi method, this study presents a systematic optimization approach for removal of lead (Pb) and mercury (Hg) by nanostructure, zinc oxide-modified mesoporous carbon CMK-3 denoted as Zn-OCMK-3. was synthesized using SBA-15 then oxidized nitric acid. The oxide loaded to modified equilibrium adsorption Zn(II) ions from aqueous solution followed calcination convert nitrate oxide. had porous structure high specific surface area which can accommodate in spreading manner, connects via oxygen atoms. controllable factors such agitation time, initial concentration, temperature, dose pH have been optimized. Under optimum conditions, pollutant efficiency (PRE) 97.25% Pb(II) 99% Hg(II). percentage contribution each factor also determined. concentration is most influential factor, its value up 31% 43% Pb Hg, respectively. Our results show that Zn-OCMK-3 an effective nanoadsorbent pollution remediation. Langmuir Freundlich isotherms were used model data
