But its potentiality as a chromogenic reagent for the trace spectrophotometric determination of heavy metal ions has not so far been explored. (2015). Spectrophotometric Determination of Cu²--Page 3 6. The method is based on the reaction of arsenic(III) with potassium iodate in acid medium to liberate iodine, which oxidizes variamine blue to form a violet coloured species having an absorption maximum at 556 nm. Lead can be present as a result of lead solder in copper piping. SPECTROPHOTOMETRIC DETERMINATION OF HYDROGEN CONTENT IN HEAVY WATER. The presence of heavy metals in the wastewater is harmful for human being. Heavy metals occur naturally in soils, but human activities lead to greater levels of heavy metals contamination in soils and to the environment.
