Determination of Sulfide in Soil and Sediment by Methylene Blue Spectrophotometry
Methylene blue spectrophotometry was applied to study sulfide in soil and sediments.When the sampling amount of 20.0 g is proper experiment,the detection limit is 0.04 mg/kg.The RSD of the six measurements was below 10.0％,and the spike recovery rate was 60％-110％.The method is simple,fast and high accuracy,and suitable for sulfide detection in soil and sediment samples.
