Large Aliquot Injection Approach in the Electrothermal AAS Determination of Arsenic in Environmental Water Samples
Determination of As by direct electrothermal atomization atomic absorption spectrometry with a pyropytically-coated graphite furnace treated with W by a single drop treatment technique was reported. The treated PG furnace made it possible to introduce a 100 µl aliquot of sample solution into the fur...
