Water quality. Determination of dissolved anions by liquid chromatography of ions - Determination of chromate, iodide, sulfite, thiocyanate and thiosulfate Ingestion-build-146508 The replacement of the terms1 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.
