查询词典 leachates

The results show that all aluminum anodizing sludges were slightly neutral to acidic and mainly consist of more than 50% Al2O3; the similar total contents of Cu, Pb, Zn, Ni, Cd, and Cr in the 7 samples were found, namely, the concentrations of Pb, Cd were relatively lower, but that of Cu, Zn, Ni, and Cr were higher; the leaching tests indicate that all the samples were classed as nonhazardous wastes; but each of metals in the sample shows very different leaching behavior, possibly depending on their total contents and the final pH of leachates.

结果表明，铝型材污泥属于中性偏酸性物质，主要由Al2O3组成，含量在50%以上。各试样中Cu、Pb、Zn、Ni、Cd及Cr的总含量的分布趋势基本是一致的，其中Pb、Cd的含量较低，Cu、Zn、Ni及 Cr的含量较高。浸出毒性试验表明铝型材污泥属于非危险废物，但污泥中各重金属的浸出特性又各自不同，可能主要与它们在试样中的总含量和浸出液的最终pH值有关。
