THIOGLYCOLATE INDICATOR
Thioglycolate (thioglycolic acid) is used in water testing as a powerful reducing and complexing agent to measure both dissolved and total iron.
Thioglycolate (thioglycolic acid) is used in water testing as a powerful reducing and complexing agent to measure both dissolved and total iron. It works by reducing insoluble ferric iron (Fe³⁺) to ferrous iron (Fe²⁺) and binding with it to form a highly visible purple complex.
Thioglycolic acid is used for the reduction of iron(III) to iron(II), and for pH adjustment. Thus only one reagent is required for analysis.
- Color Comparison: After a brief waiting period (usually 3 to 5 minutes), the color of the sample is compared against a standard color chart or measured photometrically to determine the iron level in mg/L (or ppm).
- Interferences: The formulation used in many test kits is designed to minimize interferences from other heavy metals that might be present in the water sample

2,4,6- Tris-(2’ - Pyridyl )-s-Triazine ( TPTZ ) or also can be use like 2,4,6-Tripyridyl-s-triazine. Solution of (TPTZ), .001 M were prepared by dissolving 0.312 gram of compound in a view drops of hydrochloric acid and diluting to 1 ltr with water.
