Beijing, Aug. 7 (Xinhua) -- U.S. scientists have developed A new technology that can remove 99 percent of bisphenol A (BPA) pollutants from water within 30 minutes, with convenient operation and low cost.

Bisphenol A is a chemical raw material widely used in the production of plastic products. Animal studies have found that BPA can damage the nervous system, reproductive system, thyroid gland, etc., and may increase the risk of cancer. Although the dangers of BPA to humans are still controversial, some countries have begun to restrict its use, such as banning its use in the production of baby bottles and water bottles.

Researchers from Carnegie Mellon University and other institutions recently reported in the Royal Society journal "Green Chemistry" that they invented A new technology to remove bisphenol A is divided into two steps, the first to add a catalyst called TAML to the water contaminated by bisphenol A, followed by the addition of hydrogen peroxide. These two substances will make bisphenol A in the water quickly coagulate into harmless clumps, which can be easily filtered out.

Researchers say they cultured yeast and zebrafish embryos with water treated in this way and found no developmental abnormalities typically associated with BPA contamination.

According to the report, this technique can be easily applied and promoted. Hydrogen peroxide is commonly used in the chemical industry, and one kilogram of TAML catalyst can be used to treat tens of thousands of tons of water.
