Abstract:

Hydrolysis of bis(p-nitrophenyl) phosphate(BNPP) catalyzed by Ce(Ⅲ)-barbitone complex was explored. The results indicate that the Ce(Ⅲ)-barbitone complex exhibits excellent catalytic activity for BNPP hydrolysis. The complex can increase the rate of the BNPP hydrolysis by a factor of 1.52×108 times compared to that of the spontaneous hydrolysis. The effect of temperature and pH on the catalytic activity of Ce(Ⅲ)-barbitone complex for BNPP hydrolysis was also investigated. It is found that the optimal catalytic condition is at 25 ℃ and pH 8.50.

Key words: Ce(Ⅲ), barbitone sodium, Ce(Ⅲ)-barbitone complex, bis(p-nitrophenyl) phosphate hydrolysis, catalytic activity
