中文摘要	研究了乌兰布和沙漠和库布齐沙漠颗粒物中的磷含量及其在黄河水体中对磷酸盐(P)的等温吸附行为。结果表明:(1)不同沙漠颗粒物中无机磷(IP)、有机磷(OP)和总磷(TP)含量有所差别，其平均值分别为257．70mug/g、42．65mug/g和312．39mug/g;(2)沙漠颗粒物对磷的吸附行为既受温度影响，也随颗粒物的种类不同而异，但吸附等温线均具有相同的变化趋势，且其等温吸附行为均很好地符合Freundlich模型、线性方程和Langmuir模型，达到了显著相关和极显著相关，并由Langmuir方程获得了不同沙漠颗粒物样分别在25℃、 35℃和45℃下对P的最大吸附容量在0．074～0．110mg·g~(－1)、0．054～0．131mg·g~(－1)和0．024～0．132mg·g~(－1)之间，此值可真实反映沙粒进入水体后吸附P的库容量。
英文摘要	The contents and adsorption behavior of phosphate onto particulate matter from the Wulanbuhe Desert and Kubuqi Desert in the Yellow River water system were researched．The results indicated that:(1)The contents of inorganic P(IP)，organic P(OP)and total P(TP)in different desert particles were different，and their means were 257．70mug/g，42．65mug/g and 312．39mug/g，respectively;(2)The adsorption behavior of desert particulate matter to phosphate was influenced by the temperature and different particles，but their adsorption isotherms all had the same changing tendency and fitted well with Freundlich model and Langmuir model，also were in good agreement with linear equations，showing remarkable positive correlation．Based on Langmuir equation (4)，the most adsorption capacities of P on different desert particulate matter under 25℃，35℃and 45℃were obtained and were in ranges of 0．074 to 0．110mg·g~(－1)，0．054 to 0．131mg·g~(－1)and 0．024 to 0．132mg·g~(－1)， respectively，which could really reflect the adsorption capacities of particulate matte to P after entering the Yellow River waters．
