The Chinese Academy of Sciences has developed a new material for the removal of highly toxic heavy metals in water.
On the 6th, he learned from the Hefei Institute of Material Science of the Chinese Academy of Sciences that the experts of the institute have made new breakthroughs in removing heavy metal pollutants from the water environment. They have prepared a single-crystal porous nanomaterial that can remove highly toxic heavy metals quickly and efficiently. Ionic hexavalent chromium.
The research results have been published in the environmentally renowned international journal Journal of Hazardous Materials, which the reviewers believe is “this is an interesting, novel and useful jobâ€.
Hexavalent chromium Cr(VI) is a common highly toxic heavy metal contaminant. Skin contact may cause allergies and eczema. Inhalation may cause varying degrees of hoarseness and atrophy of the nasal mucosa; ingestion may cause vomiting, abdominal pain, and cancer. And Cr(VI) may also cause genetic defects and have a persistent hazard to the environment.
According to experts from the Chinese Academy of Sciences, in many Cr(VI) treatment methods, photocatalysis is an efficient and clean treatment method by photocatalytic reduction of highly toxic Cr(VI) to low toxicity and essential for human body. III), can effectively reduce the harm of chromium ions.
Researchers from the Institute of Intelligent Science of the Chinese Academy of Sciences conducted systematic research on Cr(VI) high-efficiency photocatalytic materials. They prepared a single crystal porous nanomaterial. Experiments show that the porous structure causes a large number of sites with high catalytic activity on the surface of the nanosheet. This nanomaterial is put into water, and the catalytic reduction rate of Cr(VI) can reach 100%, and at the same time, it can be used for organic pollutants such as benzene and phenol. The catalytic degradation rate is also greatly improved.
This research work was supported by the National Major Scientific Research Project “Basic Research on Applying Nanotechnology to Remove Micro Pollutants in Drinking Waterâ€, the Chinese Academy of Sciences “Introduction of Outstanding Overseas Talents†and the National Natural Science Foundation Project.

Faucets Hose
There are 2 kinds of faucets hose has 2 kinds, flexible hose and shower hose. Flexible hose use to connect faucet to angle valve or water pipe. The thread of joint size may be different in different countries. Other shower hose only has length difference, it often 1.5m or 1.2m hose. These two faucets hose made of stainless steel or PVC.
