PREPARATION OF IODINE-INCLUDED CARBON USING RF PLASMA CVD T.Uchiyama1,Y. Sakamoto2,M. Takaya2 (1.Graduate School, Department of Precision Engineering, Faculty of Engineering, Chiba Institute...) Abstract:For the aim of synthesis of the carbon-iodine compound, the preparation of iodine-included carbon using RF plasma CVD was studied. Iodine-included carbon was synthesized on Si substrate using ICP......
carbonate as a precipitant. The results indicated that an extremely loose YAG precursor was obtained when iodine was intro-duced in the coprecipitation process on the condition that the initial...-persed particles with an average grain size of 30 nm and better sinterability. The present results indicated that the modified coprecipitation method, with iodine as an additive, was superior......

method with using acetonitrile as solvent. The influence of iodine doping concentration in acetonitrile solution on the structure, topographic and optical properties of CuI thin films was investigated. X-ray diffraction results showed that CuI iodine-doped films doped CuI?I2 were in γ-phase of zinc blende structure with (111) preferential plane. Scanning electron microscopy revealed......
碘化法从废弃印刷线路板中浸取金徐渠1,陈东辉1,陈亮1,黄满红1(1.上海市东华大学环境科学与工程学院生态纺织教育部重点实验室)摘 要:研究用碘化法从废弃印刷线路板中浸取金的过程.结果表明,碘化法从废弃印刷线路板中浸取金的合理条件为:碘的质量分数为1.0%~1.2%,n(I2)∶n(I-)=1∶8~1∶10,助氧化剂双氧水的质量分数1%~2%,浸出时间4h,固液比为1∶10,浸出温度为常温(25℃),溶液pH值控制在中性.此时金浸出率可达95%.碘化法浸取金具有环保,高效,药剂易回收等优点.关键词......
