火山渣对地下水中Cd2+的吸附效果
AdsorptionEffectonCd2+byScoriainGroundwater
摘要
Abstract
Aimingattheproblem ofCd2+pollutionin water,theexperimentofCd2+adsorptionby ecologicallysafescoriainlow temperature water wascarriedout,and weanalyzedtheeffectand influencefactorsofCd2+adsorptionbyscoria.TheresultsshowthatscoriaisakindofCd2+adsorbent withpotentialvalue.Theremovalratereaches97.10%in0.5mg/LCd2+solutionusing1.00gscoria at10℃.The neutralenvironmentis conducive to adsorbing Cd2+.Ca2+,Mg2+ and NO-3 in groundwatercaninhibittheadsorptionofCd2+byscoria,whileFe2+and Mn2+havelittleinhibitory effect.WhenthemassconcentrationsofNH+4 andNO-2 arelessthan50 mg/L,theyhavenoeffects ontheadsorptionofCd2+byscoria.Whenthemassconcentrationsaremorethan50mg/L,theyhave inhibitoryeffectsontheabsorption.SO2-4 hasnoeffectontheadsorption.HCO-3 withhighermass concentrationhaspromotioneffectontheadsorptionofCd2+byscoria.关键词
