氯化铜脱除硫化氢气体制硫磺研究
cupric chloride H2S oxidation
2009/3/5
A novel technology of removing H2S with cupric chloride solution was developed in this paper. Cupric as the form of CuS deposition, the CuS produced was then oxidized by excessive cupric ion i...
simple chemical method was employed to coat carbon nanotubes with a layer of copper. Due to the hydrophobic nature, large surface curvature, small diameter and large aspect ratio, it is difficult to ...
It is observed by scanning tunneling microscopy (STM) that the adsorbed Benzotriazole (BTA) on copper is long in shape and has an irregular rectangle. The growth of BTA on copper is in the form of p...
对乙氧羰基硫脲和丁黄药组合捕收剂方案浮选德兴铜矿进行了小型和工业试验研究。结果表明，与丁黄药单一捕收剂方案相比，组合捕收剂方案可使石灰用量降低2/3，实现铜铁混合精矿在pH值为10.5左右的高效浮选分离，显著提高矿山铜、金和钼的回收率。采用普遍化微扰理论和密度泛函B3PW91/6-31G(D)计算对上述实验结果进行了理论分析。ECTU的反应中心为硫代羰基中的硫原子，ECTU的最高占据分子轨道与次最...
报道了一种新的高灵敏度非水溶性卟啉显色剂meso-四(5-溴-2-羟基苯基)卟啉的合成方法，并研究了该试剂与铜反应的条件。研究结果表 明，在pH3.0的HCl-NaAc缓冲介质中和SDS-吡啶-镉存在下，沸水浴加热12min反应进行完全。在最大吸收波长417nm处，配合物的表观摩尔吸光系数ε值是4.01×105L·mol-1·cm-1，铜量在0～160μg/L范围内符合比尔定律。方法应用于废水、人...
