摘要: Sorbents based on Chromaton N-AW with layers of mesoporous silica gel modified acetylacetonate nickel (II) and copper were obtained. The porous structure sorbents synthesized industrial samples N, Silipore 075, Silochrom C-120 was studied. All studied are mesoporous. For commercially available Silochrome 120, the mesopore dimensions vary in a wide range from 10 to 50 nm. chelate-containing sorbents, narrower pore distribution is observed 5-15 nm, which indicates uniformity its surface. A comparative analysis effect carrier properties acid-base surface carried out. nature modifier more pronounced case by sol-gel method.
