Conclusion The use of SPE procedures has been growing in the past few years due to their
advantages offered for trace element determinations, namely conservation of species, good …

An overview is presented dealing with the use of pure, chemically modified, and sol‐gel‐
derived silicates for designing electrode materials that are then exploited in various …

Increased utilization of mechanically stable synthetic matrices particularly silica gel as a
solid support and its surface modification either by impregnation of organic ligands directly …

The magnetic removal of Hg2+ from water has been assessed using silica coated magnetite
particles. The magnetite particles were first prepared by hydrolysis of FeSO4 and their …

The immobilization of gallic acid on the surface of amino group-containing silica gel phases
for the formation of a newly chelating matrix (GASG) is described. The newly synthesized …

Silica-supported dithiocarbamate adsorbent (Si-DTC) was synthesized by anchoring the
chelating agent of macromolecular dithiocarbamate (MDTC) to the chloro-functionalized …

Silica gel/chitosan composite (SiCS) was prepared via., sol–gel method by mixing silica gel
and chitosan and cross-linked with bifunctional cross-linker glutaraldhyde. The SiCS …

In this study, a composite composed of polyaniline and silica gel was successfully prepared
via in situ polymerization. The prepared polyaniline/silica gel (PANI/SiO 2) composite was …

Two silica gel phases loaded with dithizone were synthesized based on chemical binding
and physical adsorption approaches. The stability of a chemically modified dithizone phase …

The speed at which selected reactants are reaching active sites grafted on porous silica gels
of various nature and porosity was evaluated using some model systems: protonation of …
