一般描述
Dowex Optipore® V-493 is a polystyrene-divinylbenzene hydrophobic resin. It has large surface area, exhibit high capacity for organic compounds and with good desorption properties, performs better at low metal concentrations.
应用
Dowex Optipore® V-493 was used in determination of cadmium(II) and lead(II) after their solid phase extraction as dibenzyldithiocarbamate chelates by flame atomic absorption spectrometry.
DOWEX OPTIPORE® L493 的干燥型，适于气态应用：挥发性有机物和危害性空气污染物。该树脂的疏水性强于活性炭，且不具有催化活性。过去被称为 XUS-43493.01。
