Title Photometric method for determining polidazol in air
Original title Fotometričeskoe opredelenie polidazola v vozduhe [in Russian]
Bibliographic information Oct. 1984, No.10, p.56-57. Illus. 2 ref.
Abstract Polidazol concentrations are measured by changes in the light absorption of coloured solutions of calcium dithizonate as a result of the reaction of zinc ions with dithizone. Colour density is measured in the range 500-560nm. The method enables polidazol concentrations as low as 0.05mg/m3 (1/2 MAC) to be determined in 100L of air sampled at a rate of 10L/min. Its analytical limit is 2Ág polidazol, at a precision of ▒3.53%.
