Characteristics of the lapis chloriti analyzed by the terahertz time-domain technology

As a traditional mineral medicine, Lapis Chloriti has attracted much attentions in recent years. Based on the components determined by the X-ray diffraction, the Lapis Chloriti were characterized by the terahertz time domain spectroscopy. Results show that the absorption of sample has positive correlation with concentration. The more mass with Lapis Chloriti, the more absorption. And the absorption becomes more intense with the particle size increasing. In addition, the absorption influenced by other factors are also compared and discussed.
