capability of D318 resin for Cr(Ⅵ) was investigated by chemistry analysis. Experimental results show that D318 resin has the best adsorption ability for Cr(Ⅵ) at pH=3.16 in HAc-NaAc medium...(Ⅵ) is 3?2. Cr(Ⅵ) adsorbed on D318 resin can be eluted by 5%NaOH-5%NaCl quantitatively. Key words: Cr(Ⅵ); D318 resin; adsorption; desorption; dynamics; thermodynamics ......
高钛渣加碳氯化反应热力学在熔盐氯化中的应用居殿春1,严定鎏1,李向阳1,马恩权2,臧颖波2,李俊强2(1.北京市钢铁研究总院先进钢铁流程及材料国家重点实验室2.攀钢集团锦州钛业有限公司,辽宁锦州 121005)摘 要:通过对高钛渣各组分氧化物加碳氯化反应的热力学计算与分析,发现循环氯气中的氧气与石油焦的燃烧反应是影响熔盐氯化炉温度的主要因素,而炉温的稳定控制是提高熔盐氯化炉运行效率的关键;在900~1 500 K时,高钛渣加碳氯化热力学趋势表明:所有氧化物在氯化过程中全部转变为氯化物,但实际反应中Al2O3,尤......
