termodifikasi arginin dengan senyawa penggandeng glisidoksipropiltrimetoksisilan …

Modification of silica coated on magnetic material iron sand with chitosan for adsorption of
Au (III) has been carried out. Magnetic material (MM) from iron sand was separated using an …

This work aim to study sorption-desorption of Au (III) onto silica modified quaternary amines
(SMQA) in gold mining effluent. Synthesis SMQA was conducted by methylation silica …

Rice husk ash (RHA) was used to prepare sodium silicate, which in turn was functionalized
with 3-(chloropropyl) triethoxysilane employing the sol-gel technique to form RHACCl …

Two novel materials of 2-aminobenzimidiazole (AB) and 1-(o-tolyl) biguanide (TB) modified
silicas coated on the iron sand magnetic material (MM@ SiO2/AB and MM@ SiO2/TB) have …

From biomass residues, organic-inorganic hybrid polymeric compounds have been
synthesized with a high ability to adsorb metal ions Co (II), Ni (II), and Cu (II) from their …

Oxidation of N-isopropyl glyphosate with aqueous hydrogen peroxide catalyzed by Au
nanoparticles supported on the quasi-graphitic mesoporous carbon materials proceeds …

Platinum, naturally found in a few parts of the world, is one of the most widely used precious
elements and its recycling from waste components is very important due to demand …

Two new sorbents, silica gel modified with Cystine (Sig-Cys-SS-Cys) and silica gel modified
with N-Benzyloxycarbonyl-L-Methionine (Sig-Z-Met-OH) were prepared and examined for …
