Abstract AITranslate

The LaB6 sample was dissolved with dilute nitric acid,and then its boron content was determined by acid-base titration with EDTA as the masking agent and mannitol as the complexing agent of boronic acid.Sample dissolution methods,reagent dosage,judgment methods of titration end-point,interfering elements,recovery ratio and precision were investigated.Operation with the method is simple and fast,and the method has good accuracy and precision with boron recovery of 99.45% ~100.48% and RSD less than0.50%。
