摘要
本文在大量实验资料的基础上,系统地研究了溶液中多种阳离子对土壤吸附铜定量的影响规律,建立了金属离子单独干扰的二元溶液吸附模型和多种离子共同干扰的多元溶液吸附模型,并对各金属离子的影响程度进行了评价。最后指出其环境水文地质意义。
there are many metal cations existing in the solation of ground water, Owing to the equilibrium of cation exchange between the metal cations and their adsorption phases on the suface of soil grains. it is essential to consider the disturbing action when studying the adsorption capacity of heavy metal cations by soil. In order to evaluate the purifying, ability of soil for heavy cations, this paper systematically discusses the influc(?) of various cations on the adsorption of copper by soil, (?)tablishes the absorption models of the binary solction of single metal cation's disturbance alone and of the multiple solution of many (?)tal cations disturbarce together, and cvaluates the infl(?) degree of various metal cations. The signi(?) of these models in envir(?)tal hydrogerlogy is pointed out at the end of the paper.
