the main sources of human exposure to trace metals for non-occupationally exposed individualsare inhalation and ingestion. because the absorption rates of the metals by inhalation are significantly higher (up to 50-60%) than those by ingestion (between 3% and 10%), determination of trace metals in ambient air samples is of special interest. the main purpose of this study was to determine fe, zn...

a highly convenient, selective and sensitive procedure for pre-concentration, separation and determination of sub-ppm levels of cu 2+ in aqueous samples based on modification of octadecyl silica bonded phase membrane (osbpm) disks is described using benzildithiosemicarbazone  (bdsc) as a powerful modifier. it was revealed that each loaded osbpm disk with 6.0 mg of bdsc serves as excellent bead ...
