Figure 4

(a) The recovery kinetics of CdSe QDs at 430 nm in water at pH 4.1 (line 1), in the presence of PAA (line 2) and PAA-g-Fe2S2 (line 3); (b) the recovery kinetics of CdSe QDs at 430 nm in water at pH 4.1 (line 1), in the presence of PAA and PEI (line 2), and PAA-g-Fe2S2 and PEI (line 3). Concentrations: CdSe QDs (1.6 × 10−5 mol·L−1), PAA (0.25 g·L−1), PAA-g-Fe2S2 (0.25 g·L−1), PEI (0.46 g·L−1), pH 4.1.
