| Abstract: | Determination of strontium in water by air - acetylene flame atom absorption method was done with adding 10 percent lanthanon nitrate solution and NaCl and KCl to eliminate disturbance from ionization which enhanced the sensitivity. The linear scope is 0.05 -5.00 mg/1, and the limit of diction is 0.01 mg/1 and the recovery rate is 90 - 104 percent. |
