COLUMN-HUB FOR CONTROL trace impurities, is recovered from the polymer building materials based on polyvinyl chloride

摘要

Column hub may find application in the analysis of trace impurities released from the polymer building materials based on PVC, as well as control data trace in the environment. Hub column tube is filled with a sorbent from a copolymer of styrene and divinylbenzene. Copolymer previously irradiated with ionizing radiation in the range polgloschennyh doses of 18 ... 625 Gy at a temperature from - 196 to 200 ° C. Copolymer irradiated in an environment of radiation-polymerizable hydroxyl-containing monomer. Irradiation occurs radiation grafting monomer to the copolymer. The grafted copolymer has an increased ability to specific interactions sorbate / sorbent and accordingly chromatographic polarities. Improved chromatographic polarity leads to an increase in the adsorption column Hub capacitance and increase the recovery rate of volatile substances. 1 NC 13 and ZP f ly-1-yl.
