Abstract
Adsorption behavior of Cu（Ⅱ） ions from wastewater of new chemically modified material MCM-41（mobil composition of matters） was studied.Two new kinds of material（Al-Ti-MCM-41 and Ti-Al-MCM-41） have been chemically modified with Al,Ti ions.The sample of Al-Ti-MCM-41（1∶1） was characterized by nitrogen adsorption and desorption isotherms data.The adsorption of Cu2＋ on the modified materials was investigated.The effects of adsorbent dosage,temperature and initial concentration on the adsorption capacity were investigated in detail.The results showed that： The pore volume of Al-Ti-MCM-41was 0.04 cm3/g,the BJH （Barret-Joyner-Halenda） average diameter was 17.02 nm.Cu2＋ was adsorbed quantitatively to the Al-Ti-MCM-41,and the absorption ratio was 99.95%.The adsorption capacity and removal percentages of Cu2＋ decreased with the adsorbent dosage increased but increased with the initial concentration increased.A higher temperature was in favor of adsorption.关键词
