摘要

Investigates the process that Nocardia is adsorbed onto the diatomite from Changbai Mountain area in Jilin Province PRC, with the effects of adsorption time, diatomite dosage, initial pH value of solution and adsorption temperature on the adsorptivity discussed. The results showed that the diatomite used has a favorable adsorbing effect by which the adsorbing process is so quick that an equilibrium is attainable for about 20 min. A good result can be attained in a range of pH value from 7.0 to 9.0. Temperature has no significant effect on adsorbing process. The adsorbing effect can be improved further by adding dosage of diatomite properly for a certain Nocardia concentration. Scanning results revealed that the surface pores of diatomite and mycelia on Nocardia surface are possibly the main adsorption location.
