Electrochemistry of chitosan amino-glycan and BSA protein mixture under seawater conditions

Dissolved Trace Metals and Organic Matter Distribution in the Northern Adriatic, an Increasingly Oligotrophic Shallow Sea

“…N-POM comprises protein-like material and is part of the SAS. Only the protein-like molecules present in seawater enable a specific catalytic hydrogen evolution reaction when adsorbed on the HMDE surface [35]. Consequently, a catalytic peak H was recorded in CPS.…”

How do certain atmospheric aerosols affect Cu-binding organic ligands in the oligotrophic coastal sea surface microlayer?

“…42,43 Peak H appears in a slightly alkaline solution such as seawater due to the hydrogen evolution reaction catalysed only by the adsorbed protein-like material. 44 CPS was performed under the following conditions: E a −0.6 V, t a 60 s, 120 s or 180 s, stripping current I str = −3 mA, −4 mA, −5 mA (seawater samples, simulated BB and dust leachate), −15 mA (model pollen solution) and maximum measurement time 3 s. In contrast to previous CPS quantications of proteinlike material in seawater samples using a calibration plot constructed with the concentration range of a standard protein, 42,43 here we used the BSA standard addition method for the rst time. In this way, peak H was successfully detected by adjusting t a and I str for each sample, which would not have been possible using a preconstructed calibration plot, because of the unexpectedly high amounts of protein-like material in SML samples.…”
