Nonylphenol is hydrophobic organic micro-pollutants, proning to react with the sediment detritus of substance. This study adds nonylphenol and 0.02% Thimerosal of rivers suspension sediment, using 0.1 M HCl and 0.1 M NaOH adjusting the pH to 4.00、6.00 and 8.00 later. The result is that Nonylphenol could be easily extracted at pH 4.00 and not be extracted easily at pH 8.00. The reaction of nonylphenol with fulvic acid at room temperature was carried out by adding MW> 1000（FA）and MW <1000 fulvic acid respectively. MW< 1000 (FA) is better than MW >1000.Because of its less molecular weight and bigger body surface area, fulvic acid can adsorb more nonylphenol. The three kinds of texture ,quartz sand, mud of Dali bridge, mud of Lixin junior high school at the bottom,are analyzed in the experiment. Mud of Lixin junior high school at the bottom has the best adsorption of NP.And the mud contains numerous of organic carbon along with different adsorption and ionic strength.However, quartz sand is inert material had few adsorption of NP.
