Determination of Calcium Chloride and Magnesium Sulfate in Compound Electrocular Irrigating Solution

Objective： To establish a novel method for determination of calcium chloride and magnesium sulfate in the compound electrocular irrigating solution by FAAS. Method： Calcium chloride was determined by FAAS with Fuel-lean flame; magnesium sulfate was determined by FAAS with neutral flame. Result： The detection limit of calcium chloride was 0.5μg·ml^-1 and the recoveries（ n = 9 ） were 98.18 % - 100.64% , RSD （n = 9） were 0.76%. The detection limit of magnesium sulfate was 0. 002μg·ml^-1 and the recoveries （ n = 9） were 99.11% - 100.76% , RSD （ n = 9） were 0.56%. Conclusion： The method is rapid , accurate and reliable.
