內(nèi)蒙古西部入黃河沙漠顆粒物磷形態(tài)研究
摘要: 用改進(jìn)的Ruttenberg分析方法對(duì)不同粒徑黃河上游主要入河沙漠顆粒物磷的形態(tài)分布特征進(jìn)行了研究.烏蘭布和沙漠和庫(kù)布齊沙漠顆粒物中磷以自生鈣磷為主,其次是碎屑磷.黑風(fēng)口沙樣中總磷含量較高,磷也以自生鈣磷為主,其次是有機(jī)磷.計(jì)算了沙漠顆粒物中生物可利用磷的含量.烏蘭布和沙漠每年向黃河輸送約1.1萬(wàn)噸總磷,其中可交換磷為492t.庫(kù)布齊沙漠每年向黃河輸送約9200t總磷,其中可交換磷約為688L Abstract: In this paper, an improved Ruttenberg analytical method was used to study the speciation of phosphorus in the inflow sand of the Yellow River. In samples from Wulanbuhe and Kubuqi desert, Ca-bound phosphorus is the dominant species, and residual phosphorus is secondary. Total phosphorus content is higher in samples from Heifengkou. Ca-bound phosphorus is also the dominant species, followed by organic phosphorus. The bio-available species of phosphorus in the sands are calculated. The Wulanbuhe desert transports 11000 tons of TP into the Yellow River annually, and the content of exchangeable phosphorus is 492 tons. The Kubuqi desert transports 9200 tons of TP into the Yellow River annually, and content of exchangeable phosphorus is 688 tons. 作 者: 郭博書(shū) 楊宏偉 周新革 王培鵬 張志 GUO Bo-shu YANG Hong-wei ZHOU Xin-ge WANG Pei-peng ZHANG Zhi 作者單位: 內(nèi)蒙古師范大學(xué)化學(xué)與環(huán)境科學(xué)學(xué)院,呼和浩特,010022 期 刊: 環(huán)境化學(xué) ISTICPKU Journal: ENVIRONMENTAL CHEMISTRY 年,卷(期): 2009, 28(6) 分類(lèi)號(hào): X13 關(guān)鍵詞: 形態(tài) 磷 沙漠 黃河.
