T
he amount of quantum dots released to various
environmental media is likely to increase in parallel with
the increase in their production and use. There is a need
for more research on fate and transport of quantum dots
in the environment. This study focused on phase transfer
of three types of core-shell CdSe/ZnS, InP/ZnS, CuInSe/ZnS
quantum dots from organic phase (toluene/hexane (1:2) to
water phase. The effect of Natural Organic Matter (NOM,
humic acid concentrations of 5- 10- 20- 50-100 ppm) and
ionic strength (0.01M, 0.02M, 0.03M KCl) on phase transfer
rate were investigated. Phase transfer was characterized by
multiple techniques including infrared and UV/Vis absorption
spectroscopy, electron microscopy, FTIR spectroscopy and
ICP-MS. This study aims to advance our understanding on
destabilization and transport of quantum dots that have
varying elemental composition for design for environment.
