摘要

沉积层（Sapropel）是湖泊底部堆积的一层由有机和无机物质组成的沉淀物。这些湖泊的水通常含有较多的重金属，如镉、铬、铜和锌，会对人类健康造成危害。无患子可用作生物吸附剂，从水溶液中去除这些重金属。我们测试了 1 至 50 克/升的不同无患子剂量和 15 至 150 分钟的不同混合时间。使用最小剂量的无患子（50 克/升）时，从水溶液中去除镉（93%）、铬（31%）、铜（84%）和锌（84%）的效率最高。研究表明，混合无患子 15 分钟足以去除铬，30 分钟足以去除镉和铜，60 分钟足以去除锌。

Investigation on applying sapropel for removal of heavy metals (cadmium, chromium, copper, and zinc) from aqueous solutions

Sapropel is a layer of sediment composed of organic and inorganic substances that accumulates at the bottom of lakes. The water of such lakes often have elevated levels of heavy metals such as Cd, Cr, Cu, and Zn, which can pose risks to human health. Sapropel may be used as a biosorbent in removing these heavy metals from aqueous solutions. Various doses of sapropel ranging from 1 to 50 g/L and different mixing times from15 to150 minutes have been tested. The maximum removal efficiencies for Cd (93%), Cr (31%), Cu (84%), and Zn (84%) from aqueous solutions were achieved using the minimum doses of sapropel (50 g/L). The study has shown that mixing sapropel for 15 minutes is sufficient for the removal of Cr, 30 minutes for Cd and Cu, and 60 minutes for Zn.

期刊介绍： Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
