A simple, sensitive and rapid method for determination of trace anions (chloride, nitrite, bromide, nitrate and sulphate ion) in concentrated inorganic acids (hydrochloric, nitric, phosphoric and sulphuric) has been developed. Each sample is diluted lOWOO-fold in water and neutralized with sodium hy
The hydrogen peroxide is oxidized at + 1.5 V vs. SCE at a glassy carbon electrode of the wall-jet type. The samples are diluted about 100 times in a dispersion coil before entering the amperometric detector. The calibration curve is linear from 10' to 1 M H&j,, when 5-rl samples are used. With 50-rl
