University, Changsha 410082, China;)Abstract:The electro-polymerization behavior of aniline in reverse (W/O) microemulsion was investigated. The experiment results show that the cyclic voltammetry polymerization behavior of aniline in W/O microemulsion is different from that in aqueous solution remarkably. With the increase of scan cycle, the oxidation potential shifts positively and the reduction......
DDTC-Ag测定三氯化铁中砷 肖郁惠1 (1.四川宜宾市卫生防疫站,宜宾,644000) 摘要: 三氯化铁作为净水剂已有多年,由于聚合氯化铝的出现而受到冷落.因铝在水中的残留,近年来三氯化铁又重新受到重视,并对其性能进行研究,现已成功研制出能稳定两年以上的液体产品和固体产品.本文参照GB/5750-1985生活饮用水标准检验法加入氟化钠掩蔽铁,对三氯化铁中砷进行测定,具有灵敏度高,准确度好,样品不需要前处理等优点. [全文内容正在添加中] ......
