摘　　要：在草酸钠存在下用紫外光照射铁（Ⅲ）溶液， 产生的铁（Ⅱ）对铬（Ⅵ）进行滴定， 并对土壤、自来水、矿泉水等实际样品进行分析，The titration of chromium(Ⅵ) with iron(Ⅱ) generated by the photochemical reaction of iron(Ⅲ) with ultraviolet light in sodium oxalate medium was described. End point was indicated by the formation of iron(Ⅱ) phenanthroline complex. It was applied to the determination of chromium in the samples with satisfactory result.
