多孔掺杂型钛系离子筛的制备及吸附性能
Preparation and adsorption properties of porous doped titanium series
摘要
Abstract
With 52.40 nm PMMA microspheres as template, the templates were filled with the prepared precursor solution. The template removed by the method of temperature-programmed roasting to synthesize the porous doped Li4Ti4.98Zr0.02O12ion sieve. The ion sieve was acid-modified with 0.100 mol·L-1 hydrochloric acid and characterized by XRD, SEM, saturated exchange capacity, pH curve to test the structure of the ion sieve and adsorption performance. The results show that the prepared ion sieve has a spinel structure with a pore size of about 50 nm. The spinel structure after acid modification has not been destroyed. Ion-sieve exchange capacity is 6.43 mmol Li+·g-1, and it has higher selectivity to Li+.关键词
