Формирование оксигидратов иттрия и циркония в присутствии неионогенного ПАВ

Abstract

Исследовано влияние широко распространенного неионогенного смачивателя ОП-10 (октилфениловый эфир декаэтиленгликоля) на физико-химические свойства оксигидратов двух разных по основности металлов - циркония и иттрия. Изучены сорбционные свойства, термолиз и морфология поверхности образцов, полученных без ПАВ и при концентрациях ОП-10 в маточном растворе, при которых ПАВ образует молекулярные растворы, сферические и цилиндрические мицеллы. Оксигидрат циркония в присутствии ОП-10 в маточном растворе формирует сфероидальные наночастицы, максимальная доля которых наблюдается при концентрации ОП-10, соответствующей образованию сферических мицелл. Оксигидрат иттрия формирует палочкообразные наночастицы, при концентрации ОП-10 в маточном растворе, соответствующей формированию цилиндрических мицелл. Оксигидраты циркония и иттрия, полученные при оптимальной концентрации ОП-10, имеют на порядок более высокие сорбционные свойства, чем образцы, синтезированные без ПАВ. The effect of widespread nonionic penetrating agent OP-10 (octyl phenyl ether of decaethylenglycol) on physicochemical properties of oxyhydrates of two metals varying in basicity, zirconium and yttrium, has been investigated. Sorption properties, thermolysis and surface morphology of the samples, obtained without surfactant agent and with OP-10 at such concentrations in mother solution that make the surfactant form molecular solutions, spherical and cylindrical micelles, have been studied. Zirconium oxyhydrate prepared with OP-10 present in mother solution forms spheroidal nanoparticles, maximum quantity of which is observed at OP concentration corresponding to that of the spherical micelle formation. Yttrium oxyhydrate forms rod-like nanoparticles at OP-10 concentration in mother solution corresponding to that of the cylindrical micelle formation. Zirconium and yttrium oxyhydrates obtained at optimal OP-10 concentration have higher sorption properties by an order of magnitude than the samples synthesized without a surfactant.
