【摘要】：文中用一种连续萃取方法(SEDEX)分析了内蒙古西部沙漠63μm颗粒物磷的五种形态:可交换态磷P_(ex);铁结合态磷P_(Fe);自生碳酸盐氟磷灰石+CaCO_3缔合磷P_(au);由岩屑形成磷灰石磷(P_(det))和有机磷(P_(org))。研究得出以下结论:1)内蒙古西部沙漠颗粒物中的磷以Pau为主,在自然粒径的颗粒物样品中P_(au)在154.44~1836.66mg·Kg~(-1),P_(au)含量与颗粒物粒径成反比,即粒径越小,含量越高。其次是P_(det),含量在8.12~477.72mg·Kg~(-1)。其他两种较易被生物利用的P(P_(ex)、P_(Fe))的总和为19.71~44.63mg·Kg~(-1),占TP的0.27%~8.51%;2)两种粒度相比,TP含量顺序均为甘肃临泽巴丹吉林(阿右旗)巴丹吉林(嘎顺诺尔)乌兰布和(巴彦高勒)腾格里(阿左旗)巴丹吉林(八道桥)。作为沙尘暴源头,63μm颗粒物易形成高空飞尘,飘过我国东部海区至太平洋,远距离输送了磷。
[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.
