The adsorption behavior of walnut shells in the presence of colloidal gold for thallium(I) ions from aqueous solution was investigated. The thallium content in the samples before and after contact with walnut shells was determined by differential pulse anodic stripping voltammetry. The adsorption capacity was studied in relation to the function of equilibrium time, the amount of adsorbent, the concentration...
This study focused on determining thallium content in tobacco samples collected from a commercial cigarette brand commonly available in Poland (manufactured by Philip Morris). The samples were analyzed with the use of differential pulse anodic stripping voltammetry (DPASV) coupled with a flow injection analysis (FIA) system. The obtained results confirmed that thallium was present in the studied tobacco...
