Other claims from this paper (11)
- Observation Diffusion coefficients in barley wax ranged from 10 −17 to 10 −22 m 2 s −1.
- Association Diffusion coefficients declined rapidly as solute molar volume increased.
- Observation Size selectivity was stronger for long-chain linear molecules than aromatic compounds.
- Mechanism Authors infer that natural wax compounds and pesticides became trapped in different wax fractions.
- Observation Long-chain aliphatic compounds appeared incorporated in crystalline wax.
- Observation Cyclic pesticide molecules appeared confined to amorphous wax regions.
- Observation Wax constituents were mobile.
- Observation Small linear aliphatic molecules had mobilities similar to cyclic pesticides.
- Observation Hexadecanoic acid had a diffusion coefficient of 3.81 × 10 −18 m 2 s −1.
- Observation Dotriacontane had a diffusion coefficient of 4.07 × 10 −22 m 2 s −1.
- Association Doubling carbon number reduced mobility almost four orders of magnitude.
