摘要：
The quantity of an anionic material in a sample is determined by adjusting the pH of the sample to place the material in nonionic extractable form, extracting out the material, spectrophotometrically measuring the extracted material, and comparing the measured value to a standard in order to determine the quantity of the anionic material.
