Simple, easy to use and selective method of Al(III) sorption–spectroscopic (SS) determination was proposed. For this purpose, silica modified with tridecyloctadecylammonium chloride(SGII) using adsorption technique and glass slide modified with thin silica–poly(dimethyldiallyl-ammonium chloride) (SGI) composite film obtained by sol–gel technique were worked out. It was shown that lumogallion (LG)...
Hemoglobin (Hb) and myoglobin (Mb) were incorporated into a porous silica network by a sol-gel method using tetraethoxysilane as precursor and cetyltrimethylammonium bromide (CTAB), poly(styrene sulfonate) (PSS) and Nafion as template additives. Three types of composite films were made on glass and pyrolytic graphite (PG) surfaces: silica-CTAB with Mb or Hb (SG-I); silica-CTAB-PSS with Mb (SG-II-Mb);...
