阳离子交换系数及其在地下水Pb污染研究中的应用

Exchange coefficients of cations and their application to the research of the lead contamination in groundwater

本文首先计算了地下水中常见阳离子与被吸附Pb2 +的交换系数 ,在此基础上利用实际地下水水质资料计算了天津市浅层地下水含水介质吸附阳离子的当量分数 ,并利用吸附Pb2 +的当量分数估算了含水介质吸附Pb2 +的量及地下咸水中Pb2

This paper calculates firstly the exchange coefficients between the common in groundwater and the absorbed pb 2+. Based on the resuts the data of groundwater quality, the equivalent fractions of absorbed cations for the upper aqueous mediums in the Tianjin city are the equivalent fraction of absorbed pb 2+, the contents of absorbed pb 2+ and the increase contents of pb 2+ in the saline groundwater are estimated.
