1.氯化氧锆在0.1M氯化钾、溴化四甲铵或硝酸钾底液中的水解极谱波与锆的浓度成正比,可用来测定氯化氧锆的含量。 2.氯化氧锆的水解在浓度10~(-2)-5×10~(-4)M(0—40°)时按下式进行: ZrOCl_2+H_2O=ZrO(OH)C1+HCl 3.水解极谱波的id/Cm~(2/3)t~(1/6)比同浓度盐酸氢离子的为小,认为是锆盐存在下,溶液的粘度增加,氢离子的扩散系数较小的缘故。氯化氧锆水溶液的pH值此按氯化氧锆浓度计算的值为大,但与同浓度的盐酸溶液的pH值相接近,因此认为是活度系数的影响。
1. Hydrochloric zirconium chloride in 0.1M potassium chloride, tetramethylammonium bromide or potassium nitrate in the hydrolysis of the polarographic wave is proportional to the concentration of zirconium can be used to determine the content of zirconyl chloride. 2. The hydrolysis of zirconyl chloride is carried out at a concentration of 10 -2 to -5 × 10 -4 M (0-40 °) as follows: ZrOCl 2 + H 2 O = ZrO (OH) Cl + HCl 3 Hydrolyzed polarographic wave id / Cm ~ (2/3) t ~ (1/6) than the same concentration of hydrogen ion hydrogen is small, that is the presence of zirconium salt, the solution viscosity increases, the diffusion coefficient of hydrogen ions than Small reason. The pH value of aqueous zirconium oxychloride solution is large based on the zirconium oxychloride concentration, but is close to the pH value of the hydrochloric acid solution at the same concentration. Therefore, it is considered as the activity coefficient.
