| Abstract: | the fluorin in the stannum concentrates was determined by the ion-selective electrde method in the system of sodium cirate, potassium nitrate and tri-alcoholic amine. The effects of pH, TISAB addition amount, stannum, aluminum and other co-exist elements were discussed. The results show that standard deviation is less than 0.02% and recovery ratio is in the range of98%~101%. |
