Preparation of Modified Kaolin and Its Properties of Water Retention

摘要：

　　Kaolin was modified by propionamide in the present study.XRD analysis with X-ray diffractometer of Rigaku Corporation,infrared analysis with a Nicolet Magna–IR750 Fourier transform infrared (FTIR) spectroscope and the analysis of the TG and DTA curve with Composite Thermal Ana-lyzer were carried out.A Plant Growth Chamber was used to study the water-retaining property of modified kaolin.The results demonstrated that the microstructure of modified kaolin was flaky.Using the modified kaolin in arid regions the sub-surface moisture of soil can be maintained effectively,and the seedling survival rate increases obviously.
