Other alkali metal persulfates are not recommended as the alkali metal persulfate in view of cost activity etc. Geological Survey ( USGS) between October 1,. Alkaline potassium persulfate digestion followed by colorimetric determination of NO 3 À was used to determine total N in the K 2 SO 4 extracts ( Cabrera Beare 1993).01086 Persulfate Digestion Method Method 10071 0. The photochemical efficiency φ for the decomposition of persulfate by light of λ254 mμ is determined by comparison with φ for the uranyl oxalate actinometer.
Filtered samples are dispensed into glass culture tubes dosed with alkaline persulfate reagent, digested in an autoclave at 250 o F ( 121 o C) , capped tightly 17 lb/ in 2 ( 117. Whole- water samples are dispensed into glass culture tubes digested in an autoclave at 250 o F ( 121 o C) , capped tightly, dosed with alkaline persulfate reagent 17 lb/ in 2 ( 117. The powder activator component further contains an alkalinity agent to ensure an alkaline bleach product when the product components are mixed.
Evaluation of Lime Persulfate Treatment for Mixed Contaminant Soil from Plum Brook Ordnance Works ( Sandusky OH) Victor F. Microbial biomass N. Soil Science Society of America Journal Abstract - Alkaline Persulfate Oxidation for Determining Total Nitrogen in Microbial Biomass Extracts.
2 kPa) for 1 hour. Alkaline persulfate digestion was evaluated ground- water samples in a large- scale , accurate, validated as a more sensitive, less toxic alternative to Kjeldahl digestion for routine determination of nitrogen , phosphorus in surface- geographically diverse study conducted by U.
