New CHEMetrics Test Kit for the Determination of Total Phosphate in Water
Nov 14 2012
CHEMetrics’ new Total Phosphate Test Kit using screw cap vials, utilizes the ascorbic acid method and measures those forms of phosphate that are converted to orthophosphate during an acid oxidation digestion. Perform digestion and measurement in the same vial. Use CHEMetrics V-2000 photometer for direct readout in ppm or spectrophotometer capable of accepting a 16 mm diameter cell.
Based on USEPA Methods for Chemical Analysis of Water and Wastes, Method 365.2 and 365.4 (1983).
Control and monitoring of phosphate concentrations in wastewater are critical before water is released back into the environment. Discharge of wastewater containing high levels of phosphate may cause excessive algae growth which causes taste and odor problems in drinking water supplies and oxygen depletion and death of aquatic organisms in surface water. Sources of phosphate include surface-applied fertilizers, commercial cleaning preparations, boiler water conditioners and drinking water treatment chemicals.
