Method 8034

Powder Pillows

Scope and Application:
reporting wastewater analyses (digestion required)**
* Adapted from Standard Methods for the Examination of Water and Wastewater
** Federal Register, 44(116) 34193 (June 14, 1979)
Tips and Techniques
• Digestion required. See 2.3 Digestion in the Laboratory Practices section of the DR/2400 Procedures Manual.
• If only dissolved manganese is to be determined, filter the sample before acid addition.
• For more accurate results, determine a reagent blank value for each new lot of reagent. Follow the procedure using deionized
water in place of the sample. Subtract the reagent blank value from the final results or perform a reagent blank adjust
