malachite green from water samples is developed using a sodium dodecyl sulfate coated
alumina solid phase. The effects of pH, flow rate of sample solution, and foreign ions on the
sorption of malachite green have been investigated. Two micrograms of malachite green
from 250 mL of aqueous phase could be quantitatively extracted into a 500 mg of SDS
coated alumina. The collected malachite green molecules were eluted with 2 mL of …
