A direct spectrophotometric method for the simultaneous determination of nitrate and nitrite by column preconcentration has been developed. Nitrate is reduced to nitrite in a copper-coated cadmium column which is then treated with azo dye reagent by column preconcentration, and the absorbance due to

Nitrite reacts with 3-nitroaniline in the presence of hydrochloric acid to form a diazonium cation, which is subsequently coupled with N-(1-naphtyl)ethylenediammonium chloride to form a stable purple azo dye. The method is suitable for the determination of 0.01-0.80 pg ml-' nitrite. The reactions ar
A sensitive and rapid method for preconcentration of aluminum has been developed by using naphthalene-methyltrioctylammonium chloride (Aliquat-336s) adsorbent. Aluminum ion forms a complex with Eriochrome cyanine R that is retained by the adsorbent in the column at pH 6 with a flow rate of 1 ml min
The feasibility of using a silica-based immunosorbent for the selective on-line preconcentration of several phenylurea pesticides in drinking and surface waters was demonstrated. The immunosorbent was packed in a precolumn which was used in the same way as a conventional C,, or PLRP-S precolumn: per
