Аннотация:In this work, the reverse sol-gel method was used to synthesize aluminum-zirconium oxide (AlZr) materials modified with ytterbium oxide, nonionicpolymer and supported nickel oxide. The specific surface area and porosityof the xerogels with different heat treatment and Ni+2 were determined by lowtemperaturenitrogen adsorption. The adsorption capacity of xerogels was studiedby photometry in relation to p-nitrophenol of anionic form and anionic(methylene orange) and cationic (methylene blue) dyes.
