Investigation of organometallic compounds adsorption in cigarette smoke via extracted humic acid

Cigarette smoke contains organometallic compounds of Cr, Pb, Ni, Co, As, Se and V. Consumption of cigarette causes to exchange of Ca, Zn and Fe in body by these metals or association of them and derange of body systems.Humic acid (HA) contains functional groups such as COOH, (OH), C=O and connect easily with multivalence cation, chelate groups and some oxides. Humic acid is appropriate absorbent for metal compounds. In this study humic acid was extracted from soil then leachated and added to cigarette filter. Organometallic compounds are adsorbed on the humic acid extracted by methanol and then studied by Gas Chromatography/Mass Spectrometry (GC-MS). The results of this study identifed organochelate compounds of carbonyl, alkyl, acetate, halide, cyclic, alken, phenyl and alkaloid. At last about 60 organometal compounds adsorbed by HA. Adsorption order of organometallic compounds so as follow: Boron > Iron > Cobalt > Manganese > Aluminum > Chromium > Lead > Selenium > Tin > Copper > Vanadium > Cesium > Germanium, Zinc, Nickel, Bismuth, Titanium, Arsenic, Molybdenum, Thallium, Rhodium, Tellurium, Rhenium
