摘要
Tourmaline was proposed as a multi-functional purifying agent to reduce the safety and health risks of drinking water. After heat treatment at different temperatures, some tourmaline FTIR absorption peaks intensity were weakened or even disappeared and peaks position were translocated. Low-temperatures treated tourmaline could quickly adjust acidic solution to weak alkaline. Moreover, there was a tendency to adjust strong alkaline solution to weak alkaline. After heat treatment at 800℃, the tourmaline could remove fluoride ion and heavy metal ions effectively, and the removal rates was more than 64% and 96%, respectively.
