BS EN ISO 10304-3-1997 水质.用离子液相色谱法测定已溶解的阴离子.铬酸盐,碘化物,亚硫酸盐,硫氰酸盐和硫代硫酸盐的测定
Water quality. Determination of dissolved anions by liquid chromatography of ions. 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.
