A modi.i.d hydrophi.i. penta-bi.muth hepta-oxi.e ni.rate （Bi.O7NO3） surface was synthesi.ed vi. a preci.i.ati.n method usi.g Ti.2 and Ag as modi.i.d agents. The synthesi.ed product was characteri.ed by di.ferent analyti.al techni.ues. The removal effi.i.ncy was evaluated usi.g mono- and di.sulphonated azo dyes as model pollutants. Di.ferent ki.eti., i.otherm and di.fusi.n models were chosen to descri.e the adsorpti.n process. X-ray photoelectron spectroscopy （XPS） results revealed no noti.eable di.ferences i. the chemi.al states of modi.i.d adsorbent when compared to pure Bi.OTNO3; however, the presence of hydrophi.i. centres such as Ti.2 and Ag developed posi.i.ely charged surface groups and i.proved i.s adsorpti.n performance to a wi.e range of azo dyes. Dyes removal was found to be a functi.n of adsorbent dosage, i.i.i.l dye concentrati.n, soluti.n pH and temperature. The reducti.n of Langmui. 1,2-mi.ed order ki.eti.s to the second or fi.st-order ki.eti.s could be successfully used to descri.e the adsorpti.n of dyes onto the modi.i.d adsorbent. Mass transfer can be descri.ed by i.tra-parti.le di.fusi.n at a certai. stage, but i. was not the rate li.i.i.g step that controlled the adsorpti.n process. Homogenous behavi.r of adsorbent surface can be explored by applyi.g Langmui. i.otherm to fi. the adsorpti.n data.

研究区位于北京市西北部,属于中朝板块华北地台(南北延伸1000公里,东西延伸1500公里)的一部分。该地区是研究华北地台寒武系层序地层学的良好场所,在苗岭统上部发育了大规模的鲕粒滩,具体位于徐庄组、张夏组和崮山组的颗粒滩沉积代表了华北地台寒武纪独特的沉积特征。根据年代地层背景下沉积相的叠加模式和旋回性,下苇甸剖面寒武系整体可划分为7个三级沉积序列(DS1-DS7),苗岭统(毛庄组、徐庄组、张下组、崮山组)则可划分为4个三级层序(DS1-DS4),其中毛庄组不发育颗粒滩沉积,徐庄组为混合潮坪相沉积,而至张下组和崮山组沉积期则转变为碳酸盐缓坡。层序由“TST+CS+HST”向“CS+HST”的变化表明了碳酸盐台地从未成熟期向成熟期的转变。深—中缓坡相组成的泥晶灰岩向上转变为鲕粒滩相灰岩是华北地台寒武纪苗岭期最基本的沉积特征。这些块状鲕粒灰岩是相对海平面下降阶段的沉积响应,构成了晚期高位体系域(LHS或强迫退积体系域(FRST),位于三级层序的上部。而且,鲕粒滩的这种沉积模式不符合层序地层学的标准模式:标准层序地层模式认为沉积主要发生在海平面上升期间,而在海平面下降期间形成连续的侵蚀不整合。此外,文章还详细描述了鲕粒的一系列特征,如鲕粒大小、组成、形态和内部组构等,并在显微镜下系统研究了放射-同心鲕、泥晶鲕、表皮鲕、复合鲕、假鲕、变形鲕等不同鲕粒的特征。鲕粒主要碳酸盐矿物为方解石及其不稳定的多晶型文石和白云石。一些鲕粒中的暗纹层很可能显示了丝状蓝藻参与鲕粒的形成过程,它们通过钻孔破坏鲕粒皮层,这些钻孔之后被文石填充。寒武纪苗岭统鲕粒的形态特征表明其是在高能浅水环境中形成且微生物作用活跃。北京西郊下苇甸剖面受层序地层控制的鲕粒滩形成模式,为华北地台寒武纪苗岭统区域对比和古地理重建提供了重要线索和研究方向。
