Table 3. Metal Analysis of Green- and Chemically Synthesized CdO NPs Yield and Total Waste in NPs Synthesisa,b.
| sample | yield of NPs (mg) | conc. of Cd in CdO NPs (μM)c | theoretical waste Cd (μM)d |
|---|---|---|---|
| Ch-CdO NPs | 840 | 1756.8 | 1053.2 |
| Cs-CdO NPs | 304 | 631.19 | 2178.81 |
| As-CdO NPs | 390 | 805.83 | 2004.17 |
a
Concentration of Cd in salt used for the synthesis of NPs was 2810 μM.
b
As-CdO-NPs (A. scoparia-synthesized), Cs-CdO-NPs (C. sativa-synthesized), and Ch-CdO-NPs (chemically synthesized CdO-NPs).
c
Assuming that the NPs were purely CdO.
d
Cd in salt – Cd in NPs.
