In this work,the snail shell/hydroxyapatite/chitosan composite was prepared as *** adsorption potential of the composite was studied for simultaneous sorption behavior of Zn(Ⅱ)and Cu(Ⅱ)ions in a batch *** and hydroxyapatite(HAP)were extracted from shrimp shell and bone ash,respectively,so this is a low cost natural *** prepare the composite,chitosan was dissolved in acetic acid,then HAP and snail shell powders were added to the chitosan *** morphology and characterization of the composite was studied by SEM and EDX *** adsorption was used to measure the amount of the *** parameters were optimized with Design Expert Software and five parameters such as the concentration of ions,pH,adsorbent amount and contact time were studied at room *** value for the parameters of Zn(Ⅱ)and Cu(Ⅱ)concentrations,pH,adsorbent dose,and contact time were 3.01 mg·L^(-1),5.5,0.02 g and 95 min,*** adsorption isotherms for Zn(Ⅱ)and Cu(Ⅱ)showed Langmuir and Tempkin,*** and equilibrium studies showed the experimental data of Zn(Ⅱ)and Cu(Ⅱ)ions were best described by the pseudo-second-order *** on thermodynamic show the adsorption process were physical and spontaneous.
