Abstract
An embodiment provides a method for measuring a halide in a sample, including: adjusting the pH of the sample with an amount of p-Toluenesolfonic acid (p-TSA); introducing silver 2, 4, 6-Tripyridyl-s-triazine (silver TPTZ) and an amount of iron (II) to the sample to make a reaction solution, wherein the sample comprises an amount of a halide; and measuring, using a color method, the amount of the halide in the sample by measuring an intensity of the absorbance of the reaction solution. Other aspects are described and claimed.

A method for measuring a halide in a sample, comprising:
- adjusting the pH of the sample with an amount of p-Toluenesolfonic acid (p-TSA);
- introducing silver 2, 4, 6-Tripyridyl-s-triazine (silver TPTZ) and an amount of iron (II) to the sample to make a reaction solution, wherein the sample comprises an amount of a halide;
- and
- measuring, using a color method, the amount of the halide in the sample by measuring an intensity of the absorbance of the reaction solution.
A measurement device for measuring a halide in a sample, comprising:
- a measurement chamber;
- a sensor to detect a colorimetric change;
- a processor;
- and
- a memory storing instructions executable by the processor to:
- adjust the pH of the sample with an amount of p-Toluenesolfonic acid (p-TSA);
- introduce, into the measurement chamber, silver 2, 4, 6-Tripyridyl-s-triazine (silver TPTZ) and an amount of iron (II) to the sample to make a reaction solution, wherein the sample comprises an amount of a halide;
- and
- measure, using the sensor, the amount of the halide in the sample by measuring an intensity of the absorbance of the reaction solution.
A product for measuring a halide in a sample, comprising:
- a computer-readable storage device that stores executable code that, when executed by a processor, causes the product to:
- code that adjusts the pH of the sample with an amount of p-Toluenesolfonic acid (p-TSA);
- code that introduces, into the measurement chamber, silver 2, 4, 6-Tripyridyl-s-triazine (silver TPTZ) and an amount of iron (II) to a sample to make a reaction solution, wherein the sample comprises an amount of a halide;
- and
- code that measures, using the sensor, using a color method, the amount of the halide in the sample by measuring an intensity of the absorbance of the reaction solution.
