Abstract
A new, simple, selective and sensitive method for the spectrophotometr ic determination of antimony in rain water is described. It includes p reconcentrating Sb with surfactants (i.e. cetylpyridinium chloride (CP C) and Triton X-100 (TX-100)) into toluene and allowing the extract to react with a dye, i.e. brilliant green (BG). The value of apparent mo lar absorptivity is 5.55x10(5) L-mol(-1)-center-dot-cm(-1) at lambda(m ax)=620 nm; the detection limit is 3 ng/mL Sb in rain water at 3-fold preconcentration.
