It has been shown that the kinetics of these two samples is rather different. The rate of leaching of Ca(VO_3)_2 is controlled by the parallel reactions between Ca(VO_3)_2 with Na_2CO_3 and NaHCO_3 respectively. No reaction occurs between NaCaVO_4 and Na_2CO_3 at least in the experimental range of the present study, the leaching rate of NaCaVO_4 with NaHCO_3 is controlled by the chemical adsorption of HCO_3~- ions on the solid surface. 收稿日期: 1983-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 刘后元 柯家骏 陈家镛 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I6/72 1 冯光熙;何晋秋;黄祥玉;李国良;和树桐;徐国胤;罗发印;葛书华;洪秉信,成都科技大学学报,1 (1981) ,1． 2 刘福臻;徐国胤;田平荣;稀有金属,2 (1981) ,20． 3 柯家骏;李道文;李希明;岳良东;冯光熙;黄祥玉;何晋秋;李国良;葛书华,高等学校化学学报,3 (1982) ,98． 4 朱秀松;李军,化工冶金,2 (1980) ,161． 5 Harte, C.
