Summary: Validation of the determination of amino acids on
laboratory prepared plates was performed. Chromatograms were recorded using
a Datacolor DC 3890 reflectance spectrometer, Camag Turner 11 densitometer
and Leco 2001 image analyzer. The precision, detection limit and limit of
quantification for each method were determined.
Keywords: Quantitative chromatographic analysis, validation, laboratory prepared plates

Summary: The sorption behaviour of dissolved orthophosphate in the
presence of humic substances has been evaluated by studying the sorption of
suspended particles (sand, calcite, bentonite, hematite). The influence of
pH and salinity was studied. It was found that, depending on salinity, the
following effects could be considered:
- reduced phosphate fixation due to the favorable sorption of humic
sbstances
- enhanced sorption induced by increased salinity and formation of
insoluble complexes.
Keywords: Humic substances, phosphates, competitive sorption, interaction

Summary: A new procedure for isolation and determination of 90Sr in
real natural samples is presented. It consists of bringing natural samples
in a soluble form suitable for separation on an ion-exchange column,
separation of calcium from strontium by means of the anion exchanger
Amberlite CG-400 and 0,25 M HNO3 in methanol as eluent.
Keywords: Radioactive strontium, separation, determination

Summary: The influence of pretreatment on capacity and selectivity
of natural zeolites for Zn and Mn has been studied. Natural tuff was
converted into Na+-form by conditioning with 2 M NaCl at 22 oC and 70 oC.
The amount and composition of exchangable cations were determined.
Keywords: Natural zeolite, ionic exchange, zinc, manganese, zeolite pretreatment

Summary: Elementary and phase composition as well as surface
morphology of the electric furnace slag were determined. The base of slag
is made from phases containing Fe, Mn and Ca. Grains differ in size and
shape, they are stuck to one anotheer into bigger or smaller agglomerated,
depending on separated fractions. With identified phases distribution
quantification by the separated fractions, the necessary phases separation
possibility by means of successive fragmentation adn screening the average
slag sample was noticed.
Keywords: Electric furnace slag, phase compositon

Summary: Anions from blast furnace slag (F-, Cl-, Br-, NO3-, NO2-
and SO42-) significantly influence the environment, human health and the
stability of structures. Particular attention is paid to reactions between
the slag and the solution of the anions in question in the duration of 1
hour to 30 days.
Keywords: Slag, anion, ion-chromatografy

Summary: A possibility of mutual separation of calcium and strontium
on an anion-exchange column has been studied and then used in working out
methods of separation of radioactive strontium from natural samples. All
examinations showed that calcium could be completely separated from the
strontium on the column with the anion exchangeer Amberlite CG-400 and 0,25
M solution of HNO3 in methanol as eluent.
Keywords: Radioactive strontium, calcium, separation
