ISO 10304-3-1997 水质 离子色谱法测定溶解性阴离子 第3部分 铬酸盐、碘化物、亚硫酸盐、硫氰酸盐和硫代硫酸酯的测定
Water quality - Determination of dissolved anions by liquid chromatography of ions - Part 3: Determination of chromate, iodide, sulfite, thiocyanate and thiosulfate
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.
