Abstract PTA welding is applied to deposit Ni-based and Co-based materials on the key parts in petroleum and chemical industry, for the purpose of surface modification. The test shows that this process is played an important role in upgrading the materials performance of anti-wear, anti-corrosion and high temperature resistance, prolonging service life, saving expensive materials and reducing production cost.

Arsenic Pollution

Antimony and arsenic are recognized to be toxic carcinogens. With the development of chemical industry, antimony and arsenic pollution problems are becoming more and more serious in soil. This paper described speciation analysis of antimony and arsenic in soil in the latest technical progress. Speciation analysis of arsenic and antimony which use joint techniques and non joint techniques are summarized. This paper also introduced various remediation technologies for antimony and arsenic contaminated soil. Finally, the trend for future technical development in remediation of antimony and arsenic in contaminated soils and speciation analysis is prospected.
