| The Bohart-Adams equation is modified for evaluation of solid phase extraction (SPE) efficiency. A relationship between sorption conditions and sorption characteristics at SPE is described. An essential influence of sorption rate factor on the efficiency of SPE, besides the generally regarded distribution factor, is revealed. A linear decrease of solution breakthrough volume versus reciprocals of influent concentration and sorption rate factor is deduced. The SPE limits of phenol and resorcinol on a sorbent Bakerbond SDB 1 are evaluated. |
