Introduction

GB/T6150.3—2023: Determination of phosphorus content in tungsten concentrate

Method 1: Phosphorus molybdenum yellow spectrophotometry

Phosphorus molybdenum yellow spectrophotometry is a classic chemical analysis method, suitable for the determination of phosphorus content between 0.005% and 1.00% by mass. This method melts the sample with potassium hydroxide, uses beryllium sulfate as a carrier to separate interfering elements such as tungsten and arsenic, then adds ammonium vanadate and ammonium molybdate color developers, measures the absorbance at 420nm, and establishes a working curve to calculate the phosphorus content.

Method 2: Inductively coupled plasma atomic emission spectrometry

Inductively coupled plasma atomic emission spectrometry (ICP-OES) is a highly sensitive modern analytical technique, suitable for the determination of phosphorus content with a mass fraction greater than 1.00% to 10.00%. This method acidifies the sample and then introduces it into the plasma source, using the characteristic spectrum line of 213.618nm for quantitative analysis, and is fast and accurate.

Method	Scope of application	Detection limit	Precision (r)
Phosphomolybdenum yellow spectrophotometry	0.005%~1.00%	0.001%	0.0012%~0.06%
Inductively coupled plasma atomic emission spectrometry	>1.00%~10.00%	0.08%	0.08%~0.34%

Background and technical evolution of the standard

GB/T6150.3-2023 replaces the original GB/T6150.3-2009. The main improvements include expanding the measurement range, adding term definitions and numerical rounding rules, and adding inductively coupled plasma atomic emission spectrometry. These changes are intended to meet the needs of the tungsten concentrate industry for products with high impurity content and improve the accuracy and applicability of analytical detection technology.

Implementation suggestions

Select the appropriate method according to the actual phosphorus content range of the sample to be tested: Method 1 is suitable for low phosphorus content, and Method 2 is suitable for high phosphorus content.
Ensure the purity of the reagents used and the accuracy of the standard solution, and calibrate the instruments and equipment regularly.
In batch testing, it is recommended to conduct a blank test for each batch of samples, and randomly select some samples for repeated measurement to monitor precision.
