Abstract : the ashing loss of pb in water samples has been studied in digestive method for determination of lead by dithizone spectrophotometry ( gb 5750 - 85 ) . after the digestive conditions are improved , the digestive loss of pb in some polluted water samples is prevented . the recovery of pb rised , the accuracy and precision of the analytical date are guaranteed 文摘:对国标5750 - 85双硫腙分光光度法中消化水样时铅的灰化损失进行了探讨，针对某些污染严重的水样，改进了消化处理的条件，有效地消除了灰化损失，提高了铅加标回收率，保证了分析测试数据的精密度和准确度。
The electrode was found to decrease the solubility of dithizone in alkalescence solution and effectively minish the lose of deoxidize state of metal . third , a potentiometric sensor was prepared by adding copper diethyldithiocarbamate directly into the carbon paste mixture , and the electrode was found has nerst response to copper ion in solution . and in our research two pharmaceutical selective electrodes were fabricated by coating polyvinyl chloride ( pvc ) which contained electroactive material on carbon rod electrode 第二，利用- cd与环氧氯丙烷形成的交联聚合物（ - cdp ） （不溶性）包合了双硫腙，然后将- cdp与双硫腙包合物树脂作为修饰剂制备了碳糊修饰电极，利用阳极溶出伏安法（ asv ）测定了pd ~ ( 2 + ) ，实验发现通过包合降低了双硫腙在碱性溶液中的溶解度并且减少了金属还原态的流失，取得了较好的效果。
A review of the development of organic semiconductor composite photo - conductive materials and devices was followed by a proposal of the researching theme in this thesis . the effects of fabrication arts such as solvents , gradient , interfacial layer and configurations on the photoconductive properties of the single - layer chlorodiane blue azo / tiopc composite photoreceptors were systematically studied in chapter ii . the results showed that the solvent played a decisive role in the multiphase and multicomponent system composed of two photogeneration species ( chlorodiane blue azo and tiopc ) , a transporting material ( hydrozone ) and polymer binder ; 1 , 4 - dioxane , as an amphiphilic solvent can effectively disperse and stabilize such multiphase and multicomponent systems , the derived photoreceptors presented improved photoconductive properties superior to those of dual - layer counterparts and demonstrated the evident synergetic enhancement and complementary effects ( eg 结果表明：在由两种光生材料氯丹蓝偶氮和酞菁氧钛、传输材料萘苯腙以及聚合物介质组成的多相多组分复合体系中，分散溶剂是至关重要的因素，二氧六环作为典型的双亲性溶剂，有效地分散和稳定了该多相多组分复合体系，得到的复合单层光导体的光敏性在整体上优于双层光导体，复合材料在可见光和近红外光区分别表现出的偶氮和酞菁氧钛的光敏性(如azo / tiopc = 8 / 2 ， cgm / ctm / pc = 1 / 120 / 120时，具有明显的互补效应；在近红外光区明显高于酞菁氧钛与偶氮光敏性的线性加和，表现出协同增强正效应。
