Guest guest Posted February 17, 2001 Report Share Posted February 17, 2001 Hi, Can someone help please? I acquired a data sheet on H2O2, but not being a chemist, I am not entirely sure if this is the " unstabilized " and " preservative " free grade that generally recommended. I would like to mention just some of their specifications on the data sheet and I was hoping you could tell me if this is the correct H2O2. The data is as follows: 1. Hydrogen peroxide solution 30% medical extra pure, stabilized Ph Eur, BP, USP 2. Organic stabilizers <= 0.05% 3. Non volatile matter <= 0.02% 4. Corresponds to Ph Eur, BP, USP Contains 0.015% Na2H2P2O7, 0,01% H3PO4, 0,006% NH4NO3 as preservatives 5. Chloride <= 0,005 % Phosphate <= 0,05 % Heavy Metals <= 0,0005 % Arsenic <= 0,002 % Copper <= 0,002 % Lead <= 0,001 % Zinc <= 0,002 % Are these values significant or are they of academic interest or do they constitute an unpure hydrogen peroxide. It seems, however, that this is the purest I will get. Your feedback will be highly valued. Regards, Johan Quote Link to comment Share on other sites More sharing options...
