2.1.Preparation of nanoparticle lanthanum borate
A total of 25.0 g lanthanum nitrate and 46.3 g borax (20% excess) were dissolved in 100 ml of distilled water,respectively,at 323 K.The lanthanum nitrate solution was dropped to the borax solution while stirring.The solution was filtered with suction.The precipitate was washed six times with 30 ml of distilled water.The water in the precipitate was replaced with n-butanol under an azeotropic distillation.The precipitate,100 ml of ligroin and 200 ml of n-butanol were added to the flask of a Dean–Stark and were heated.Where the cooled water was separated from the mixture solvent in oil–water separation tube and the solvent was returned to the flask.The distillating was stopped when the boiling point of the solvent stopped rising or the volume of the water in oil–water separation tube stopped increasing
