Hi,
Can somebody enlighten me on the requirement of chemical composition for NaCl.The grade I'm looking for is extra pure and ASTM B 117 specifies that the salt used shall be free of nickel and cooper and contains not more than 0,1% of sodium iodide and max 0.3% of total impurities.I need to know how to establish other elements/compounds not specified.These are required for Salt Spray analysis for Sulfuric acid and Chromic acid anodizing(AMS 2470 & 2471).Thanks for advise.
