Abstract

Two novel adsorbents (AGD301 and ArgD301) were successfully prepared through ring-opening reaction. The adsorption performance and recognition selectivity of AGD301 and ArgD301 towards AuCl4− were studied by batch adsorption experiments. The results showed that adsorption time, pH, temperature and solution concentration had a significant influence on the adsorption performance. At 298 K and pH of 2, the equilibrium adsorption capacity of AGD301 and ArgD301 towards AuCl4− could reach 400.75 and 451.67 mg·g−1, respectively. In addition, AGD301 and ArgD301 possessed excellent selectivity and good reusability. [ABSTRACT FROM AUTHOR]

8. Preparation of activated carbon based on hair and its selectively removing ability for Fe(III) from La(III)

Abstract

It is of great significance to effectively remove impurity such as Fe from rare earth elements because the trace of Fe(III) have serious damage to the performance of rare earth materials. In this study, a hair-based activated carbon (ACH*) was synthesized and characterized by surface area analyzer, Fourier transform infrared spectroscopy and elemental analysis. The identification and removal of the performance of ACH600 for Fe(III) in the La(III) solution was studied. The adsorption capacity of ACH600 for Fe(III) was 15.54 mg/g and the removal rate reached up to 98.6% by virtue of abundant nitrogen-containing functional group. The selectivity coefficient of ACH600 for Fe(III) was 8.3 relative to La(III). In addition, the ACH600 also has good regeneration and reusability.
