The result shows that 0 . 22 cucl / 4a adsorbent exhibits superior properties . thirdly , cu - based activated carbon adsorbents were systemically investigated , some of which were characterized by bet and xrd . the pericarp activated carbon ( ac ) made in chengde was found to be a better support either 系统研究了cu型活性炭吸附剂，并进行了结构性能表征，发现承德果壳炭性能较好，适合于作为载体使用；母体则采用氯化亚铜效果最好，氯化铜次之，其它铜盐效果很差。
On the basis of electroplating and immersion plating tin , and through large numbers of experiments , a new process of electroless plating tin in acid chloride bath solutions including sncl2 2h2o , nah2po2 h2o , special complexing agent , additive agent , stabilizing agent and antioxidant , was established . continuous self - catalyzed deposition of tin on copper substrate was achieved successfully , and half - bright and silvery - white tin deposits with excellent properties were obtained 本文是在电镀锡、浸镀锡工艺配方的基础上，通过大量的试验，确立了一种以氯化亚锡、次亚磷酸钠和特定的络合剂、添加剂、稳定剂，抗氧化剂为基本镀液组成的酸性氯化物化学镀锡体系，成功地在铜上实现了锡的连续自催化沉积，获得了性能优异的半光亮银白色锡镀层。
The experimental results of the catalysts such as p - toluene sulfonic acid , strongly acidic cationic exchange resin , sulfo - polyvinyl chloride resin ferric chloride hexahydrate , polyvinyl chloride - ferric chloride resin chlorinated polyvinyl chloride - ferric chloride resin , stannous chloride dihydrate , ammonium ferric sulfate dodecahydrate , ferrie sulfate - potassium thiosulfate , cerium sulfate tetrahydrate , sodium bisulfate monohydrate potassium bisulfate , neodymia solid super acid and heteropoly acid for catalytic synthesis of ethyl chloroacetate were reviewed 摘要评述了对甲苯磺酸、强酸性阳离子交换树脂、磺化聚氯乙烯树脂、六水三氯化铁、聚氯乙烯三氯化铁树脂、氯化聚氯乙烯三氯化铁树脂、二水氯化亚锡、十二水合硫酸铁按、硫酸铁硫代硫酸钾复盐、四水硫酸铈、一水硫酸氢钠、硫酸氢钾、三氧化二钕、固体超强酸和杂多酸等催化剂催化合成氯乙酸乙酯的实验结果。
