| Abstract: | Determination of potassium in the production of complex fertilizer was described by titration of trimethyl hexadecyl ammonium bromide with excessive sodium tetraphenylborate. Results showed that it was three hours less than weight method and the error was less than 0.22%. The method could be used in the production control process. |
