This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...
Precious Plate, Inc. is a local electroplating company that uses a variety of metals during its processes. Post-deposition, the aqueous phase used is designated for disposal, which poses problems regarding the metal content of the waste stream. First, EPA regulations mandate that metals be kept below specific levels. Even at levels capable of meeting EPA limits, the loss of metals within their ...
COMPARITATIVE STUDY OF ADSORPTION OF Cr(VI) FROM WASTE WATER USING TAPIOCA PEEL AND BANYAN TREE ROOT
One of the most important and toxic heavy metals in wastewater is chromium. Cr (VI) is released from different industrial operations, including metallurgy, leather tanning, paint, textile industries, chemical manufacturing, pulp production, ore and petroleum refining, metal corrosion, electroplating products etc. Hexavalent chromium is toxic, carcinogenic, probably mutagenic and highly soluble....
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...
