In this study, a novel process for recovering Cr from Cr-bearing electroplating sludge (ES) was proposed, which involved the desulfurization stage and reduction-smelting stage. stage, decomposition of CaSO4 in ES promoted by adding certain amount carbon. It found that ratio increased first then decreased as increasing C/S (molar ratio) 0.5 to 2, while it monotonously temperature raised. The pro...

Electroplating waste water is considered to be harmful to health of animals. In the present study, we tested the hypothesis that electroplating waste water would suppress immune functions in Kunming mice. Twenty-six mice were randomly divided into the control group (n = 13) and the experimental group (n = 13), in which the latter drank electroplating waste water. We found that body mass and mos...

In the oxygen-enriched side-blown smelting furnace for treatment of electroplating sludge, fluent was used to simulate gas–liquid two-phase flow process. The relationship between lance diameter, inclination, bath depth, and evaluation indicators were studied, oxygen spacing optimized. results show that high velocity gas rate areas near lance, while stirring dead zones with low appeared in centr...

During the last two decades, extensive attention has been paid on the management of environmental pollution causal by hazardous materials such as heavy metals. Decontamination of heavy metals in the soil and water around industrial plants has been a challenge for a long time. A number of methods have been developed for the removal of heavy metals from liquid wastes such as precipitation, evapor...

Arsenic (As) toxicity in soil and water is an increasing menace around the globe. Its concentration both in soil and environment is due to natural and anthropogenic activities. Rising arsenic concentrations in groundwater is alarming due to the health risks to plants, animals, and human beings. Anthropogenic As contamination of soil may result from mining, milling, and smelting of copper, lead,...
