[Determination of metals in atmospheric particulates by atomic absorption spectrometric method (AAS) with CA-CN micropore membrane filters used for sampling].
A new sampling method of atmospheric particulates using 0.22 microm pore diameter micropore membrane filters was introduced. Copper, lead, zinc cadmium, manganese, iron, nickel and chromium in atmospheric particulates were determined by atomic absorption spectrometry. This sampling method has shown several advantages: easy, complete and fast digestion; low membrane blank; increased flexibility to surrounding temperature change; high elution recovery, standard addition recovery, precision and accuracy.
