Abstract: It was reported that trace amounts of Mo(VI) could inhibit the decoloring reaction of acid chrome blue k by hydrogenperoxide in acidic condition.The linear range of the method was 0~3.4μg/25ml for Mo(VI), with detection limit of 3.1×10g/ml. The proposed method has been applied to determination of trace molybdenum in vegetables with recovery of 97%~102%.

Key words: kinetic spectrophotometry, molybdenum, chrome blue k
