摘要
用空气—乙炔还原型火焰原子吸收分光光度法测定水中微量的锶，在试样中加入硝酸镧溶液（10%）、氯化钠及氯化钾消除酸对测定水中锶的干扰和共存离子的干扰并抑制了电离干扰，提高了灵敏度，线性范围0.05-5.00mg/L，最低检出限浓度为0.01mg/L，回收率为90-104%。
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.
