Water quality. Determination of dissolved anions by liquid chromatography of ions - Determination of chromate, iodide, sulfite, thiocyanate and thiosulfate1 Scope This part of ISO 10304 specifies methods for the determination in aqueous solution of the dissolved anions iodide, thiocyanate and thiosulfate (clause 4); sulfite (clause 5); chromate (clause 6). An appropriate pretreatment of the sample (e. g. dilution) and the application of a conductivity detector (CD), UV detector (UV) or amperometric detector (AD) make the working ranges given in table 1 feasible. Table 1 Applicable working ranges Anion
