原位帽封材料对水体中Pb(Ⅱ)与Cd(Ⅱ)静态吸附
Static adsorption for Pb (Ⅱ) and Cd (Ⅱ) in water by material of in-situ capping
摘要
Abstract
The capping materials were prepared by wrapping coral,chitin,and acrylic resin using nonwoven.This kind of material was applied to immobilize the heavy metal ions in situ in sediments and simultaneously adsorb Pb2+ and Cd2+ in water body.The adsorptive property of this cap sealing materials was analyzed through fourier transform infrared spectroscopy (FTIR),scanning electron microscopy (SEM) and flame atomic absorption spectro-phototometer (FAAS).The effect of pH and sorbent dosage on the absorption efficacy of above cap sealing materials was investigated.It was shown that at pH 5.0,the absorbance of Cd2+ and Pb2+peaked to 434.67 mg/g and 524.27 mg/g,respectively.The adsorbent capacity increased with the increase of the initial concentration at the constant pH and adsorbent dosage.The analysis results of FTIR and SCM indicated that this cap sealing materials had high adsorptive property.关键词
