微波非热效应改善天然石墨提纯效果
Purification of natural graphite by microwave assisted acid leaching
摘要
Abstract
Natural graphite was leached under microwave irradiation by acid mixtures containing HC1 (12 mol/L) and HNO3(16 mol/L). It was found that the purification efficiency was affected by microwave power, reaction pressure, reaction time and the acid ratio. The carbon content of the graphite increased from 95. 84 to 99. 43% under optimized leaching conditions with an acid volume ratio of 1 :1, pressure of 1. 0 MPa, reaction time of 25 min and microwave power of 800 W. SEM indicated that the morphology remained unchanged and XRD indicated that there was no apparent change in the 20 peak position, peak height and full width at half maximum after the leaching.关键词
