USE OF COLLOID ENHANCED ULTRAFILTRATION FOR THE REMOVAL OF PERCHLORATE FROM AQUEOUS SOLUTION

摘要

Perchlorate salts are highly water soluble and are, to a large extent, kinetically inert as aqueous species. As a groundwater contaminant, perchlorate seems to be most widespread in areas of southern California, but is now being found in an increasing number of locations. It is believed that perchlorate interferes with the uptake of iodide by the thyroid which can result in a decrease of hormone production. The EPA has recently established a limit of approximately 24.5 ppb perchlorate in drinking water.
