COPPER SULFATE PENTAHYDRATE ELECTROPLATING GRADE(HIGH PURITY) (Cu10D12-50) Specification Cu-10 Top GradeINDEXContent of copper sulfate (base on CuSO4.5H2O), %≥99.0Content of copper (Cu), %≥25.20Content of arsenic (As), %≤0.0005Content of plumbum (Pb), %≤0.0010Content of calcium (Ca),%≤0.0005Content of chloride(base on C1),%≤0.0010Content of cadmium(Cd), %≤0.0003Content of ferrum(Fe), %≤0.0010Content of cobalt(Co), %≤0.0005Content of nickel(Ni),%≤0.0005Content of zinc(Zn),%≤0.0010Content of hydragyrum(Hg), %≤0.0005Content of chromium(Cr), %≤0.0010Content of Polybromobiphenyls(PPB), %≤0.0010Content of Polybromodiphenyls ethers(PBDE)≤0.0010Content of insoluble substance, %≤0.0050PH value (5%, 20°C)≤3.5-4.5Characteristics Small blue and clean crystal, odorless, density:2.284g/cm3, soluble in water and diluted the solution appear weak acidity. It will be efflorescence slowly in dry air, and its surface wil become thite powder substance. It will lose four crystal water when heated to 110°C, and will be changed into white anhydrous copper sulfate which is easy to absorb water when the temperature is higher than 150°C. Uses It is for the ion additive of sulfate salt plating copper and wide temperature,high bright acidity plating copper. It is mainly used to high grade plating fields f science research, IT industry and chemical agent because the impurity contents of Fe, Ca,Pb,As,Co,Ni are lower than the copper sulfate specification of chemical agent in GB665-88 standard.
