Summary: The solubility products of mercury(II)- and
lead(II)-dodecylbenzenesulfonates were calculated on the basis of
lightscattering measurements at 20 C to be (9.33 +/- 0.90)E-13 and
(1.03 +/- 0.10)E-12, respectively. The investigations ofprecipitation
phenomena performed in diluted natural sea-water,
c(Cl-) = 1E-2 mol/dm3, including tenzide and added heavy metalions showed
similar behaviour for all metaldodecylbenzenesulfonates, investigated in
this work, i.e.synergistic effect of tenzide, of added electrolyte, cations
andanions from sea-water. Comparison made by statistic test ofsignificance
chosen to measure an agreement between the estimatesof the solubility
constants obtained in aqueous solutions and inthe above mentioned sea-water
solution, showed noticeable effectexpressed mostly in the case of
mercury(II). The precipitation oftenzide and metal nitrates in the natural
sea-water, c(Cl-) =5E-1 mol/dm3, covers wide concentration region of HDBS
(from highconcentrations to 5E-6 mol/dm3) and from high metal
nitrateconcentration to very low. The microscopic textures of
phasesprecipitated on the systems with sea-water obviously
confirmedfavorizing of the liquid crystalline phase formation.
Keywords: alkylbenzenesulfonates, heavy metal ions, lyotropic liquid crystals, sea-water, solubility product.

Summary: The formation of colloidal and liquid crystalline
aggregates of aluminium dodecylbenzenesulfonate caused by mixing aqueous
solutions of Al(NO3)3 and dodecylbenzenesulphonic acid (HDBS) was
investigated by light scattering and polarizing microscopy. Applying a
fractal approach, some aggregates can be
considered as multifractals and some as fractals, depending on the slopes
of the 'lgI(Q) versus lgQ' plots (for multifractals the slopes are greate
then 3). A model of multiscaling for the calculation of fractal dimension
in the formation
of the liquid crystalline phases is proposed, describing both the spacial
and the temporal dependence of amphiphile self-aggragation. The basic
symmetries of the dynamics of formation and the structure of the liquid
crystalline phases
were found to be consistent.
Keywords: colloidal and liquid crystals, fractals, multifractals, solubility product

Summary: The Coulombs, ionic cloud and the average potentials
of the Debye-Hueckel theory, in the space adjacent to
spherical particles, charged with a given number of
elementary point charges, can be calculated. The cited
experiments are certainly a strong support for the
correctness and usefulness of the DHT, as applied for
the point charge double layer model. Efforts to calculate
potentials were generally unsuccessful because l and 1/k
are not included in the homogeneous charge, elwctrical
double layer models, which, for these reasons, should be
abandoned.

Summary: The proof is given that in "Coagulation Kinetics"
(a)equation 1 is incorrect because it does not represent
the Rayleigh's light scattering equation correctly
(b) the experiments do not confirm in any way the DLVO
theory.
