Methods for rapid spectrophotometric determination of phosphorus from feed digested solution using non-nitrogen containing color developing reagents and methods for preparing the reagents

摘要

The present invention method for quickly and easily measured to prepare a coloring reagent for measuring a of the feed decomposed solution with a reagent not containing the nitrogen, and added it into droplets and spoon and related to his coloring reagent production method, this method is a conventional in dissolving the coloring reagent in water, or mixture as compared to a method of adding into the pipette to analyze the operation is simple and saves time to be able to reduce reagent usage, and to reduce the amount of waste liquid generated after analysis, the conventional method Although the present invention has a nitrogen in the color-developing reagent is contained in a high concentration is capable of reducing an experiment waste water treatment costs by using a reagent not containing the nitrogen.
