板栗壳对水中Cu^2＋吸附性能的研究

In order to exploit chestnut shells,a residue of the food processing industry,in heavy metal waste treatment,the ability of chestnut shells to remove copper from aqueous solution by adsorption was studied.【Method】 The effects of pH,mass concentration,dose and size of the adsorbent,contact time and temperature on the removal of Cu2+,and desorption and regeneration were studied by batch process.Breakthrough capacity and desorption were studied by column process.【Result】 Optimum adsorption conditio...
