Product Specification

 

Lanlang ® TY CH520 is a sort of chelating resin which has weakly acidic iminodiacetic acid [-CH2N-(CH2OOH)2] in the styrene / DVB copolymer with special macroporous structure. This amazing product is capable of fixing and chelating various types of cations, even in high content solutions. It is primarily utilized for separating and retrieving precious metal ions, making it especially useful for secondary refining of salt brine in cases where the content of Strontium is equal to or greater than that of calcium during the ion membrane alkaline production process. Its versatile properties make it an invaluable tool for numerous applications. CH520 is also used to remove cooper, nickel, cobalt, zinc from waste water.

 

The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), which are commodity chemicals required by industry. Thirty five million tons of chlorine were prepared by this process in 1987. The chlorine and sodium hydroxide produced in this process are widely used in the chemical industry.

 

Usually the process is conducted on a brine (an aqueous solution of NaCl), in which case sodium hydroxide (NaOH), hydrogen, and chlorine result. When using calcium chloride or potassium chloride, the products contain calcium or potassium instead of sodium. Related processes are known that use molten NaCl to give chlorine and sodium metal or condensed hydrogen chloride to give hydrogen and chlorine.
