【摘要】：文中用一種連續(xù)萃取方法(SEDEX)分析了內(nèi)蒙古西部沙漠63μm顆粒物磷的五種形態(tài):可交換態(tài)磷P_(ex);鐵結(jié)合態(tài)磷P_(Fe);自生碳酸鹽氟磷灰石+CaCO_3締合磷P_(au);由巖屑形成磷灰石磷(P_(det))和有機(jī)磷(P_(org))。研究得出以下結(jié)論:1)內(nèi)蒙古西部沙漠顆粒物中的磷以Pau為主,在自然粒徑的顆粒物樣品中P_(au)在154.44~1836.66mg·Kg~(-1),P_(au)含量與顆粒物粒徑成反比,即粒徑越小,含量越高。其次是P_(det),含量在8.12~477.72mg·Kg~(-1)。其他兩種較易被生物利用的P(P_(ex)、P_(Fe))的總和為19.71~44.63mg·Kg~(-1),占TP的0.27%~8.51%;2)兩種粒度相比,TP含量順序均為甘肅臨澤巴丹吉林(阿右旗)巴丹吉林(嘎順諾爾)烏蘭布和(巴彥高勒)騰格里(阿左旗)巴丹吉林(八道橋)。作為沙塵暴源頭,63μm顆粒物易形成高空飛塵,飄過(guò)我國(guó)東部海區(qū)至太平洋,遠(yuǎn)距離輸送了磷。
[Abstract]:In this paper, a continuous extraction method (SEDEX) has been used to analyze the five forms of phosphorus in 63 渭 m particulate matter in the western desert of Inner Mongolia: exchangeable phosphorus (PX); iron bound phosphorus (P); iron bound phosphorus (P); authigenic carbonate fluoroapatite (CaCO_3) associated phosphorus (CaCO_3); apatite phosphorus (apatite); And organophosphorus. The following conclusions can be drawn: (1) Pau is the main phosphorus in the particulate matter of desert in western Inner Mongolia. In particle samples of natural particle size, the content of PSP in 154.44 ~ 1836.66 mg 路KGG ~ (-1) is inversely proportional to the particle size, that is, the smaller the particle size, the smaller the particle size. The higher the content is, the higher the content is. The next is PSD, which is 8.12 ~ 477.72mg 路KGG ~ (-1). The sum of the other two kinds of Phe Phe, which is easy to be used in life, is 19.71 ~ 44.63 mg 路Kgfen ~ (-1), accounting for 0.277.51g ~ (2) of TP). The order of TP content is in the order of the content of TP in Badanjin (right Banner) of Gansu Province (Gashun Noor). Wu Lan Buhe (Bayan Gaole) Tenggri (Azuo Banner) Badaogan (Badaoqiao). As the source of the dust storm, 63 渭 m particulates are liable to form high-altitude flying dust. Across the eastern sea area of China to the Pacific Ocean, the distant transport of phosphorus.
