【摘要】 提出采用合成羟基磷灰石处理工业废水中铅和镉的方法,建立了处理铅、镉的最佳条件,实验了脱除效果,实验结果表明:本方法操作方便,设备简单,交换吸附容量高,能同时脱除工业废水铅和镉,一次处理后,脱除率可达89％以上,能在较广的pH范围内进行交换吸附。更多还原

【Abstract】 This paper deals with synthtic hydroxylapatite (HAP) to remove Pb2+ and Cd2+ in wastewater. The optimizating condition and removing efficiency can be determined. This method can together to remove Pb2+ and Cd2+ in wasterwater, removing rate up to remove Pb2+ and Cd2+ in wastewater, removing rate up to above 89%. It has a widely determining pH range, convenient operation, simple equipment and high adsorbing capacity. This method has a good feasibility and satisfactory result.更多还原
