WebEPA issued a Registration Standard for sodium and calcium hypochlorite in February 1986. The Agency concluded that no additional scientific data would be necessary to register or reregister products that contain sodium hypochlorite from 5.25% to 12.5%, or calcium hypochlorite from 65% to 70%, as long as the products contain no other active Webfor UV/Vis detection. The method enabled limits of detection as low as 25 ng/ml based on standard solutions. However, rapid degradation of chlorite was observed in milk. Milk samples spiked with as much as 500 ppm chlorite showed no measureable chlorite within 24 hours. Chlorite degrades as an oxidant to chloride (Cl-) which is common in milk.
