| 中文摘要 | Effects of NaOH treatment on the cobalt adsorption to bone were studied. Compared with the untreated bone, NaOH treatment increased cobalt sorption capacity of bone from 20.1-25.1 mg g(-1) to 58.75 mg g(-1). The kinetic studies demonstrated that the cobalt adsorption data for untreated bone or NaOH treated bone a-reed well with pseudo second-order equation. NaOH treatment resulted in an increase in initial sorption rate by a factor about 2 and a decrease in half-adsorption time (t(1/2)) by 40% at different temperature. Intraparticle diffusion study showed that intraparticle diffusion was not the only rate-limiting step in cobalt sorption to both untreated bone and NaOH treated bone. Both the Langmuir and the Freundlich models described the sorption data well for untreated bone and NaOH treated bone at different temperature. Thermodynamic studies showed that adsorption of cobalt to untreated or NaOH treated was endothermic but not spontaneous. Higher temperature was favorable for the sorption process toward spontaneous reaction and NaOH treatment also contributed to sorption process toward spontaneous reaction. The activation energy of sorption, E-a, was 8.01 kJ mol(-1) for untreated bone and 13.38kJ mol(-1) for NaOH treated bone, respectively, at an initial cobalt concentration of 200mg L-1 at 298K. FT-IR spectra analysis showed that ion-exchange could be the most predominant mechanism involved in cobalt sorption by bone. |
