Abstract
This investigation elucidate procedure to assessments trace cadmium (II), Lead (II), copper (II) and zinc(II) ions in an indoor airborne particulate substance sample by square wave anodic stripping voltammetry (SWASV). Various experimental trials, which affected the sensitivity of carbon paste electrode (CPE) to these metallic ions, were adjusted. Lower limit of detection of four metal ions were 0.02, 0.3, 0.03 and 0.09 μg/Kg for cadmium (II), Lead (II), copper (II) and zinc(II), respectively, with great accuracy (standard deviation is below 3 %). respectively, with identical accuracy. Interference from co-existing cations were successfully examined. A comparison of data results for assessment the actual substance was performed for graphite furnace atomic absorption spectrophotometric (GFAAS) technique and SWASV techniques. Using standard addition technique, the recovery was 98.5–103 % and standard deviation (SD) of 0.8–2.6 %. The more advantages for SWASV method is the simple, sensitive, selective and short period of analysis than that for GFAAS procedure. The suggested procedure was useful for assessment of trace cations in an indoor airborne particulate matter sample. Cations concentrations were in the same variety with the described data.
