Preparation of Modified Kaolin and its Properties of Water Retention

Abstract:

Kaolin was modified by propionamide in the present study. XRD analysis with X-ray diffractometer of Rigaku Corporation, infrared analysis with a Nicolet MagnaIR750 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.
