Keywords： tourmaline

Tourmaline can promote the growth of microorganisms under the temperature less than 900 ℃ by experiment.However,this promotion effect will vanish at 900 ℃ as a result of denaturation.Through the XRD analysis the crystal form change can explain the vanishment of tourmaline's biological promotion effect at high temperature.Therefore,tourmaline as a biological promoter was used to prepare a kind of biological promotive ceramsite with the surface area of 7.914 m2/g,pore volume of 0.1002 mg/L,superficial pH value of 7.8,Zeta potential of 25 mV,unit water absorption of 0.1365 g/g,biocompatibility of 0.023 A/g and SICE of 0.8456.The experimental results show that the biornass of biological promotive ceramsite is 3.58 times more than that of ordinary ceramsite,and the treatment effect of the biological promotive ceramsite is better than the ordinary ceramsite.These features of this new biological promotive ceramsite makes it a preferable biovector.
