Scope

This standard specifies the detection method for phosphate ions in wastewater discharged from industries (including business sites). Measured by absorbance photometry, phosphate ions react with excess ammonium molybdate solution to form a heterogeneous polymer compound (hetero-polymer compound), which is reduced by adding stannous chloride to form molybdeunm-blue. Based on the method of measuring absorbance and quantifying it. Water soluble
