WARNING: Personnel using this section should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This part of GB/T 14506 specifies the method for the determination of phosphorus pentoxide in silicate rocks. This section applies to the determination of the amount of phosphorus pentoxide in silicate rocks, and also applies to the determination of the amount of phosphorus pentoxide in soil and water system sediments. Measuring range: phosphorous vanadium molybdenum yellow photometric method, 0.2%-10% phosphorus pentoxide content. Phosphorus molybdenum blue photometry, 0.05%-2% phosphorus pentoxide content.
