Chloride, bromide, fluoride, nitrite, nitrate, sulphate and phosphate

i Chloride, bromide, fluoride, nitrite, nitrate, sulphate and phosphate 

The work of Mosko [116] is important in that he is one of the few workers who have given serious consideration to the determination of nitrite in water. His paper is concerned with the determination of chloride, sulphate, nitrate, nitrite, orthophosphate, fluoride and bromide in industrial effluents, waste water and cooling water. Two types of analytical columns were evaluated (standard anion and fast run series). Chromatographic conditions, sample pretreatment and the results of interference, sensitivity, linearity, precision, comparative and recovery studies are described. The standard column provided separation capabilities which permitted the determination of all seven anions. The fast nm column could not be used for samples containing nitrite or bromide owing to resolution problems. 

Eluent pump flow rate of 35-40% (161-184ml h ) maintained system pressure between 500 and 700psi. Both the sample and regeneration pumps were operated at 50% flow rate (230ml h ).
