1 Application scope This standard specifies 5-Cl-PADAB spectrophotometry for determination of dissolved cobalt and total cobalt in water. This standard is applicable to the determination of cobalt in surface water, industrial wastewater and domestic sewage. When the sampling volume is 20.0 mL, the detection limit of the method is 0.009mg/L, the lower limit of determination is 0.036mg/L, and the upper limit of determination is 0.500 mg/L. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For undated references, the latest edition of the normative document applies. HJ/T 91 Technical specifications requirements for monitoring of surface water and waste water 3 Terms and definitions For the purpose of this standard, the following terms and definitions apply. 3.1 Dissolved cobalt the cobalt determined after the non-acidified sample passes through a 0.45μm pore size filter membrane 3.2 Total cobalt the cobalt measured in unfiltered samples, i.e. the sum of dissolved and suspended cobalt in the sample
