Overview

Sulfur dioxide detection K-9520 method $r $n Due to the permeability of sulfur-containing minerals, sulfides are very common substances in groundwater. However, surface water usually does not contain high concentrations of sulfides, which are produced through the degradation of organic matter, the reduction of bacterial sulfates under anaerobic conditions, and various chemical processes.

Methylene blue method
Reference: USEPA Method, Chemical Analysis of Water and Wastewater, Method 376.2 (1983); APHA Standard Method, 22nd edition, Method 4500-S2-D-2000.
The CHEMetrics test kit uses methylene blue to test total dissolved sulfides, which react with ferrous chloride in the presence of ferrous chloride**The reaction of diamine generates methylene blue, and the result is expressed in ppm (mg/L) sulfur (S).
