APDTC complex

Cvetkovic and coworkers [74] evaluated a mixed Ni and Sr nitrates matrix modifier for the determination of Se in wines by Zeeman ET-AAS. Samples were heated on a boiling water bath with small amounts of HNO3 and H2O2. To eliminate interferences, especially sulfates and phosphates, Se was complexed with APDTC and extracted into methylisobutyl ketone (MIBK) and the graphite furnace temperature program was optimized for both aqueous and organic solutions. Selenium concentrations up to 0.93 pg l-1 were detected in wines from the Republic of Macedonia. 

Wastewater treatment facilities often use dithiocarbamates (DTCs) to remove heavy-metal contaminants (down to ppb levels) as DTCs form stable complexes with a wide variety of transition metals. We therefore investigated the ability of three commercially available DTCs to remove Cu from our process stream sodium dimethyldithiocarbamate (NaDMDTC, 129), sodium diethyldithiocarbamate (NaDEDTC, 130) and ammonium pyrrolidine dithiocarbamate (APDTC, 131). Upon addition of each DTC to the postcoupling reaction mixture, solid precipitates were observed that could easily be...
