| 内容記述 | To utilize air-cooled blast furnace slag (ABFS) as an intermediate soil for trapping Pb dissolved by the degradation of chelated Pb compounds after the termination of PCC, batch adsorption experiments were performed to clarify the Pb adsorption characteristics of ABFS at two pH levels (8 and 12), and the effect of Na, K, and Ca on these characteristics was investigated. The Henry model could be applied at the both pH with and without the addition of a cation at the total Pb concentration (Ce,total) as well as the available Pb concentration (Ce,av), which comprised Pb2+ and [Pb(OH)]+ at the equilibrium concentration. Na, K, and Ca had no effect on the Pb adsorption characteristics of ABFS within the investigated concentration range. The distribution coefficient Kd,total at pH 12 was 1/50 of the Kd,total at pH 8 when Ce,total, whereas the Kd,av at pH 12 was 120 times higher than the Kd,av at pH 8 when Ce,av was used. Therefore, the decrease in Kd,total with pH indicates that the influence of the formation of Pb–OH complexes on Pb adsorption by ABFS is higher than that of an increase in the negative charge density of ABFS. | |||||
