Abstract
Copper has been determined spectrophotometrically by using ascorbic ac id as a chromagenic reagent. The complex formed in basic medium is mea sured for its absorbance at 340 n.m Interference for 23 cations and 9 anions has also been checked. Effect of pH, time, temperature, ammonia reagent concentration and interferents has been reported.
