Ethylene arsenic removal agent

1、overview

The propylene arsenic-removing agent is developed by Jiangxi 866 SAN Industrial Co., LTD., which is made by a unique process with lead oxide as the main active component and special additives.

The agent has good activity, high strength, arsenic capacity and arsenic removal accuracy are up to or better than the same agents at home and abroad.

The agent is mainly used for the removal of hydrogen arsenide from materials containing alkynes.
