| 摘 要： | 以珠江广州河段沉积物为研究对象,利用红外、紫外、荧光、X射线衍射等手段研究了沉积物中有机质的结构,与其他地区相比发现其芳化度和不饱和度较高,含N量也较高.以萘为吸附质,在碱处理前后的沉积物样品做吸附实验,结果发现沉积物样品接近线性吸附,而碱处理过后却呈现明显的非线性吸附,吸附机理的差异显示与其结构有密切的关系.

| Abstract: | The structure characters of organic sediment in water were exposed using FI-IR,UV-Vis,FS,XRD.The result showed that there are more aromatics and unsaturated bonds in the organic matter.The content of nitrogen is higher than other districts.The sorption experiment was carried on in condition of the naphthalene as a sorption matter,and the sediment and residue(that distilled HA) as the adsorbents.Because of the different structure characters,the two samples have the different sorption mechanism.The sorption c... |
