INFLUENCE OF COLLOID SUSPENSIONS OF HUMIC ACIDS ON ALKALINE HYDROLYSIS
321
CV [15] to HSs is Ks = 0.13 mg−1 L, the value of
KsMNTS/KsCV is equal to 192. This value is 19 times
bigger than the ratio KsMNTS/KsCV for OTACl and 45
times bigger than the ratio of SDS. This means that the
hydrophobicity of the HS core is significantly bigger
than the corresponding one of normal micelles.
To sum up, the kinetic effect of the presence of HSs
can be modeled using the pseudophase model. The HSs
are colloid dispersions in water, and their influence on
chemical reactivity can be rationalized considering that
HSs are micelle-like colloids.
