LY/T 1253-1999 Determination of mineral total elements(silica,iron,aluminium,titanium,manganese,calcium,magnesium,phosphorus)ignition loss in forest soil (English Version)
This standard specifies the sodium carbonate alkali fusion-hydrochloric acid extraction method for melting and extracting samples; animal glue desiliconization-quality method, polyethylene oxide (PED) desiliconization-quality method, volumetric method for silicon determination and preparation system analysis of the liquid to be tested ;Determination of iron by phenanthroline colorimetry and atomic absorption spectrophotometry; determination of aluminum by volumetric method using potassium fluoride instead of EDTA; determination of titanium by chromotropic acid colorimetry and diantipyrine methane colorimetry; formaldehyde oxime colorimetry and atomic absorption spectrophotometry to determine manganese; EDTA complex titration and atomic absorption spectrophotometry to determine calcium and magnesium; aluminum antimony colorimetric method to determine phosphorus; ignition loss method to determine the loss on ignition, etc. This standard is applicable to the determination of loss on ignition of forest soil and its clay minerals (silicon, iron, aluminum, titanium, manganese, calcium, magnesium, phosphorus).
