查询词典 clay

We report here on the characterization of copper-plated screen-printed electrodes modified by different clay minerals for the same purpose. The results indicated that clay minerals could improve oxidative and reductive currents of copper through the adsorption of copper ion on the surface of clay minerals. Nontronite showed the largest improvement in reductive currents of copper among the three clay minerals studied.

In the second part, we developed a new approach for the preparation of highly dispersed carbon black platinum nanoparticle with different geometric shapes by introducing clay (0 to 33%) as a dispersing agent in 5% Nafion co-solvent suspension without any organic solvents. FE-SEM analysis of CB/clay (100/0, 85/15, 67/33) was achieved CB particles with an average diameter of 40-60 nm. The hydrophilic property of the hybrid material was effectively improved in the presence of the clay was observed in sessile-drop test.

第二部分中我们发现在燃料电池之触媒制备常利用碳黑作为载体，碳黑在水中分散程度不一，而有机分散剂之电阻质较高常导致触媒用量提高增加成本，在本论文中我们利用几何片状结构的黏粒矿物与Nafion溶液做为分散剂巧妙的将碳黑分散，在不同黏土矿物与碳黑之不同比例(clay/CB 0/100， 15/85， 33/67)下进行分散，在SEM及TEM鉴定下证明其分散程度而碳黑粒径约40-60 nm。

At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.

在痕量浓度下，研究了蒙脱石、伊利石、高岭石三种粘土矿物对Cu〓、Pb〓、Zn〓、Cd〓、Cr〓五种重金属离子的吸附容量、吸附选择性及其介质条件对吸附量的影响，结果表明，粘土矿物的阳离子交换容量越大，对重金属离子的吸附容量也越大，其大小顺序为蒙脱石＞＞伊利石＞高岭石；同时，不同粘土矿物对重金属离子具有明显的吸附选择性，蒙脱石对Cr〓和Cu〓有较好的选择性，伊利石和高岭石则对Cr〓和Pb〓有较好的选择性；随着吸附溶液pH值的增大，其吸附量有增加的趋势。
