| 摘 要： | 研究了湖南麦饭石对水溶液中无机阳离子的吸附性能和吸附后溶出性能,并探讨了吸附机理,观察了麦饭石粒度、用量、试液体积、浓度、温度、时间等因素对吸附率以及温度、时间对再溶出率的影响,结果表明:麦饭石对Cd~(2+),Hg~(2+),Pb~(2+)等有毒离子的吸附能力较强,且主要是离子交换吸附,吸附容量较大,吸附后再溶出率低.

| Abstract: | The adsorptive characteristics of Hunan medical stone for inorganic positiveion in water solution and redissolution has been studied.The effect of the size of medicalstone grains,its dosage,the volume and concentration of the solution,temperature,and timeon adsorption rate and the effect of temperture and time on redissolution rate have been ob-served.The results show that medical stone has quite strong adsorptive capacity for poisonousion of Cd~(2+),Hg~(2+) and Pb~(2+),mainly in the way of ion exchange.The redissolution rate afteradsorption is low.The adsorptive mechanism is discussed. |
