| Abstract: | The terminal point was determined by electric conductivity titration method with the use of sodium tetraphenylboron solution and consequently the content of K in molasses alcohol wastewater is obtained in this paper. The method takes the advance of simple and rapid operation and fewer reagents. The degree of accuracy approaches that of weight method. |
