Efficient Formation and Preservation of Perchlorate with Iron Salts on the Martian Surface

Experimental results of photochemical experiments using chlorine-containing substances of different valences (Chloride, chlorate and perchlorate) mixed with different sulfates (K-, Mg-, Ca-, Fe-, Na-, sulfate) and iron-containing minerals (ferric sulfate, ferric chloride, ferric nitrate, siderite, ferrous sulfide and nontronite).The conversion rates relative to the initial Cl species in each experiment were normalized and labled accordingly. In addition, the XRD data of some starting materials are also given.
