化学系承担的国家自然科学基金资助课题“稀土硝酸盐热化学研究”课题组,两年来制备了除Sc和Pm以外的15种稀土硝酸盐水合物40种;用PE TG—2热重分析仪以T D—DTG法对它们的热分解行为进行了系统、详细地研究,提出了热分解机理,总结其规律性;借助不同升温速率下的DTG曲线,用Kissinger法计算了一些脱水过程的脱水表观活化能;用PESC
Department of Chemistry, National Natural Science Foundation of China sponsored by the project “rare earth nitrate thermochemistry” project group, prepared two kinds of rare earth except for Sc and Pm 40 kinds of rare earth nitrate hydrate 40; PE TG-2 thermogravimetric analyzer Their thermal decomposition behavior was studied systematically and in detail by TD-DTG method. The mechanism of thermal decomposition was put forward and its regularity was summarized. By means of DTG curves at different heating rates, some dehydration tables of dehydration process were calculated by Kissinger method View activation energy; with PESC
