SMBS purity Na2S2O5

Question asked by Maher Mostapha on Aug 29, 2018

hello all

 

i consume and SMBS for mining purposes.

 

I have a technical question and i hope someone can help please..

 

Na2S2O5 should be above 97% or 98% as per the factory production and per contract with producer.

 

A test was conducted as follows Na% : 23.52 %. Nas was tested separately.

 

If Na% is 23%, this test alone means that the purity is low and off specs ? or it should be tested in full combination as :  Na2S2O5
