Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted by Yunnan Entry-Exit Inspection and Quarantine of People's Republic of China, People's Republic of China Xishuangbanna Entry-Exit Inspection and Quarantine Bureau Epidemic Bureau, Pu'er Exit Inspection and Quarantine of People's Republic of China. The main drafters of this standard. Liang Wenjun, Lu Ping, Liu Jun, Liang Xin Yu, Lu Ying, Chen Jie, Mei Chunfen, Fan Yun, Zhang Yuhong, Duan Min. Determination of phosphorus and arsenic in industrial phosphorus Energy dispersive X-ray fluorescence spectrometry Warning --- personnel using this standard should have the corresponding practical experience of laboratory work. Industrial phosphorus is a highly hazardous chemical, empty Spontaneous combustion of gas and the release of toxic and harmful gases; yellow phosphorus spontaneous burning easily when the skin, and the damage is extremely serious, not easy to recover; yellow phosphorus sample It must be sealed in water and in any case, yellow phosphorus can not be exposed to the air.

1 Scope

This standard specifies the use of energy dispersive X-ray fluorescence spectrometry Determination of phosphorus in industrial phosphorus, arsenic content. This standard applies to the determination of phosphorus and arsenic in industrial phosphorus, phosphorus detection range of 99.50% ~ 100.00%, arsenic detection limit of 0.0010%.

3 method summary

Determination of industrial phosphorus content of phosphorus, arsenic Elemental energy dispersive X-ray intensity, the ray intensity and pre-prepared industrial yellow Phosphorus standard samples were compared X-ray intensity, phosphorus, arsenic content of industrial phosphorus samples were obtained.

4 instruments and materials

4.1 energy dispersive X-ray fluorescence spectrometer. 4.2 industrial phosphorus standard sample, with the elemental phosphorus, arsenic content standard sample value. Industrial phosphorus standard samples can be used without industrial quality control samples of yellow phosphorus, industrial quality control of yellow phosphorus samples should have elements of phosphorus, arsenic The exact amount of the measured value. When selecting industrial yellow phosphorus standard samples, phosphorus and arsenic standard values shall cover the range of phosphorus and arsenic in the yellow phosphorus samples to be tested.

5 analysis steps

5.1 Sample Preparation Industrial phosphorus in accordance with GB/T 7816 classification, the sample in accordance with GB/T 6679 extraction. Solid yellow phosphorus at about 65 ℃ hot water (tap water plus Heat) liquefaction, mix (see Figure 1), with a glass pipette from the middle of the liquid yellow phosphorus absorption 1.6mL ~ 2.0mL analysis of the sample to a stainless steel spoon In the spoon sample, stainless steel spoon, scoop surface hot water together to move to cold water, standing, curing, made of yellow phosphorus sample thickness 2mm ~ 3mm, uniform translucent, smooth surface, no crepe or corrugated, stored in distilled water. ......
