METHOD OF OBTAINING CALCIUM ALUMINATE-BASED SORBENT FOR GASCHROMOGRAPHIC SEPARATION OF AROMATIC POLYCYCLIC HYDROCARBONS

摘要

FIELD: chemistry.SUBSTANCE: claimed is method of obtaining sorbent for gaschromographic separation of aromatic polycyclic hydrocarbons. Calcium aluminate is obtained by mixing in solution calcium nitrate, aluminium nitrate and crystalline citric acid at molar ratio of components 1:2:3. After mixing drying at 130°C and burning at 1000°C are carried out. Obtained product is mixed with solution of sodium chloride, evaporated on water bath until loose sample is obtained, dried at 120°C and incinerated at 900°C.EFFECT: increase of sorbent selectivity.3 tbl, 3 ex
