I want to know how to prepare solution of NaBH4 in water. we we know that NaBH4 is instable in the water.

Ahmed Hasham

please find attached file

centrifuge the solution at 15,000 rpm for 20 min and repeated the

centrifugation process for 3 to 4 times and filtered the resulting solution through Whatman No.1 filter paper and dry the pellet in hot air oven.

this method according http://www.ijpsr.info/docs/IJPSR12-03-03-011.pdf

Thank you Dear Hassen
