| Abstract: | The content determination techniques,the double-indicator technique and the second technique(GB4348.1) of the national standard GB/T11199-89,are introduced.Two new determination techniques,mixed-indicator technique and the technique of the national standard GB629-81,are proposed.And the application practices of chemical-agent technique on determining the content of sodium hydroxide and sodium carbonate in ion-exchange membrane caustic soda are summarized. |
