摘　　要：通过往反渗透膜处理水中加入一定量分散剂制备出分散稳定性能好的碳化钛水基溶液,并采用沉降稳定性分析、XRD分析、红外光谱分析和透射电镜观察来分析其状态。沉降稳定性分析探讨了分散剂用量对溶液沉降稳定性的影响,XRD结果表明水基溶液中的碳化钛晶相成分未发生变化,红外图谱结果表明分散剂在碳化钛表面形成了化学吸附,透射电镜观察到溶液中的纳米碳化钛基本上是以单个粒子形式存在。A certain amount dispersant was added to RO water to prepare TiC aqueous solution with well dispersion stability performance.It was analysed by sedimentation stability analysis,XRD analysis,infrared spectrum analysis and TEM analysis.The sedimentation stability analysis explored that the influence of dispersant dosage on the solution stability.XRD results showed that TiC crystal phase composition in aqueous solution kept intact.Infrared spectrum results showed that the surface of TiC was formed chemical adsorption by dispersant,TEM observed that nano TiC existed in the form of single particle.
