In this work, potassium doped and undoped Li2ZrO3-based sorbents for CO2 capture at high temperatures were synthesized through wet impregnation of Li and K salts over a colloidal suspension of zirconia nanoparticles. The ...

In this work, an adsorbent was prepared based on the attachment of organophosphorus acid extractants, namely, D2EHPA, CYANEX 272, and CYANEX 301, to the surface of superparamagnetic magnetite (Fe3O4) nanoparticles. The ...

In the present study, we report the synthesis of selective magnetite molecular imprinted polymer (Fe3O4@SiO2@NH2-Que-MIP) for the first time by a simple ultrasonic mediated co-precipitation polymerization route and applied ...

An aminopropyl-modified MCM-41 sorbent obtained by grafting amino groups on the surface of a previously synthesized MCM-41, was used for the removal of Cr(VI) and Zn(II) from different aqueous matrices: solutions of Zn(II) ...

The general goal of this study is the application of novel sorbents to eliminate the inorganic contaminants existent in samples of Chilean mining acidic aqueous solutions. They are: a) Modified nano-structured calcium ...

A first study that demonstrates the capability of the amino-functionalized MCM-41 sorbents to reduce Cr(VI) to the less toxic trivalent state is presented. To achieve this aim two mesoporous ordered silica with MCM-41 pores ...
