The wettability of carbon electrodes by the molten cryolite-alumina salts was investigated in a laboratory microelectrolysis cell.Once the direct current was imposed , the wettability of carbon cathode was immediately improved, and after several minutes the molten electrolyte would gradually spread out on the carbon plate and even separate from the anode. However, the separated electrolyte would gradually coalesce into a single drop and touch the anode once again,then the electrolysis process resumed....

The wettability of carbon electrodes by the molten cryolite-alumina salts was investigated in a laboratory microelectrolysis cell.Once the direct current was imposed , the wettability of carbon cathode was immediately improved, and after several minutes the molten electrolyte would gradually spread out on the carbon plate and even separate from the anode. However, the separated electrolyte would gradually coalesce into a single drop and touch the anode once again,then the electrolysis process resumed. By way of x-ray powder analyses the absorbed components in the cathode plate were determined to be Na3AlF6, NaF, A12O3 etc. Hence, most probably this is due to the change in the structure of the interfacial layer (due to the transfer of sodium ions-Na+、Na2+ and aluminium ions-A13+ 、A1 + into the cathodic layer) following the application of the cathodic potential and due to the resulting deposition of a film of metallic Al or Na. The wettability of carbon cathode was increased with the increasing of current density and of concentration of alumina in electrolyte. But when the carbon plate was anodically polarized, the wetting phenomena were different, especially in the region of high current densities. During the electrolysis a change of polarity of electrodes had been tested, it was observed that a sudden change in the wettability occurred. When a carbon anode was cathodized for a few seconds, its wettability would be greatly improved. Therefore a periodic change of polarity may be beneficial to the aluminium electroiysis.

在微型电解槽上研究了冰晶石——氧化铝熔液对炭电极的湿润性。通入直流电之后,电解质对炭阴极的湿润性变好,同时逐渐在炭板上摊散,甚至脱离阳极,但是它还会逐渐收敛成熔滴,最终重新接上阳极并恢复电解。阴极炭板所吸收的成份,经X-射线鉴定,主要是Na_2AlF_6、NaF、Al_2O_3。电解质对炭阴极的湿润性随电流强度增大和氧化铝浓度增加而改善。但是炭阳极的湿润性,在高电流密度下并非如此。在电解过程中做了变换电极极性的试验,短时间(数秒钟)内使阳极“阴极化”可改善阳极的湿润状态,因而有益于生产。

Moreover, the rate varied with [HCl]~(3/2) between 2~7 M hydrochloric acid. The extraction rate equation can be written as R=k[U(IV)][TOPO]_(0) The rate constant k was evaluated...

The kinetics of the extraction of U(IV) chloride in the TOPO-HCl system has been studied using the single drop technique. The effects of the concentrations of U(IV), TOPO and HCl on the extraction rate for U(IV) have been examined.The extraction rate measured were found to be of first order with respect to [U(IV)] and [TOPO]_(0). Moreover, the rate varied with [HCl]~(3/2) between 2~7 M hydrochloric acid. The extraction rate equation can be written as R=k[U(IV)][TOPO]_(0) The rate constant k was evaluated to be 3.7×10~(-5) at 3M HCl and 15℃.The extraction rate was increased with increasing temperature. The apparent activation energy was found to be 10.8 kcal/mol between 15 to 45℃. It is suggested that the rate-controlling step may be the chemical reaction of UC1_4 with TOPO at the interface and the formation of the interfacial complex UCl_4·TOPO.

本文采用上升液滴法,研究了三辛基氧化膦(TOPO)-环己烷溶液从盐酸体系中萃取U(IV)的动力学.按实验结果在一定的盐酸浓度下,TOPO箤取U(IV)的速率可由下述萃取动力学方程式表示:R=K[U(IV)][TOPO]_(0)在[HCl]=3M和15℃时,计算得萃取速率常数K=3.7x10~(-5).在不同盐酸浓度的溶液中,TOPO萃取U(IV)的速率与盐酸浓度的3/2次方成正比.测定了温度(15~45℃)对萃取速率的影响,求得萃取反应的表观活化能为10.8 kcal/mol. 由实验结果推测,TOPO从盐酸体系中萃取U(IV)的反应可能按下列两步进行:UCl_4+TOPO_(0)=UCl_4·TOPO_(0) (1)UCl_4·TOPO_(0)+TOPO_(0)=UCl_4·2TOPO_(0) (2)而生成界面溶剂配合物的反应(1)是萃取速率的控制步骤.
