查询词典 kaolinite

There are three evolution paths for the kaolinitic rocks in the diagenesis:one is that kaolinite is transformed to the mixed minerial of kaolinite/dickite and dickite in the acid environment; the second is to be trnasformed to the ammonium illite,chlorite and pyrophyllite in alkaline environment;The third is to be transformed to well ordered kaolinite in the superfacial environment. The highly orderization of kaolinite may be related to the hot solution underground.

At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.
