Questions regarding sulfide determination

2009-09-22View Original

Thread Content

GB/T16489-1996 specifies that the maximum allowable level of sulfite among the major interfering substances is 20 mg/L. If the sulfite level in the water sample exceeds this value, how should the sulfide content be determined? Increase shielding or opt for another method?

Zinc sulfide precipitation can be used to filter and separate sulfite ions, effectively eliminating their interference with the measurement
