Model substances of metal species composed of organic ligands and heavy metals were separated and detected by capillary electrophoresis. The effect of metal addition to polyaminopolycarboxylic acids on their electrophoretic mobility was studied. Meta

Sodium perborate was used for oxidation of bromide ions at pH 3.64. The reaction was conducted by potentiometric measurements. The orders with respect to perborate and bromide ions were found to be unity in each reagent and a plausible mechanism was

In the presence of molybdenum, both the uncatalyzed and the catalyzed reactions proceed simultaneously. An equation for kcat was derived and the effect of temperature was described through a temperature function F(T) by the use of the Arrhenius-Eyrin

A new catalytic method for the determination of 0.1-10 ppm molybdenum is described. Molybdenum catalyses the perborate - bromide ascorbic acid Landolt reaction at pH 3.64. The rate is monitored by potentiometry. A calibration graph is based on the ra

Calcium, phosphate and buffering capacity were measured in children's (n=43) unstimulated saliva between September 1990 and June 1991 inclusive. Saliva samples were collected in the afternoon, once a month, on 10 consecutive occasions. Buffering capa

A simple mathematical model is presented for the evaluation of analytical results which are subject to slow, linear drift. The method is very advantageous if evaluation is carried out with programmable desk or pocket calculators.
