Abstract:

The determination of total phosphorus by L-ascorbic acid spectrophotometry and hydrazine sulfate spectrophotometry is analyzed and discussed. Combined with the running indexes of circulating cooling water in power plants and actual water quality conditions, an accurate and suitable method for the determination of total phosphorus has been obtained. It is of reference value to the improvement of chemical and environmental monitoring in power plants.

Key words: total phosphorus, L-ascorbic acid, hydrazine sulfate, spectrophotometry
