'. ,. ..'-,. " Modifications Increased quantity of 5% HNOy' 10% H202 reagent in first two impingers to 1000 ml (7 impinger setup) First two impingers contained 3.5 N solution of sodium bicarbonate instead of DI water to capture sulfates and phosphates. Impinger solutions recovered for analysis. Increased strength of sodium hydroxide solution to 2 molar in third and fourth impingers Normality of frrst unpinger solution was increased to 6.1 and quantity was increased to 250 ml. Additional 6.1 N solution added during run to maintain pH. |
