| Abstract: | Sulfo-functionalized magnetic beads were prepared by covalently conjugating aminobenzenesulfonic acid onto carboxyl surface of magnetic beads with 1-ethyl-3-(3-dimethylaminopropyl)carbo-diimide(EDC)/N-hydroxysulfo succinimide(Sulfo-NHS) method.Those beads were used as dispersive solid phase extraction sorbent,and hence,a high efficient extraction procedure was developed for enriching trace amounts of malachite green(MG) in fishpond water.Parameters of adsorption and desorption of MG including pH value of fi... |
