Complex ion exchange and adsorption methods were used for drinking water purification. Na-clinoptilolite was applied for selective removal of ammonium ions. The ion exchange capacity was 0.47 mg NH4+/g, and 0.2 mg NH4+/L breakthrough concentration wa

A mathematical model between the relative error in the Kubelka—Munk (K—M) function and the sample concentration has been determined if the K—M function is linear with the sample concentration, c ≤ w/w%. The theoretical model has been investig

Nineteen air pollution point sources (emission points) for three industries, and 16 deposited dusts within and around a highly polluted city were sampled. Morphological, mineral and elemental composition of dust were determined. It was found that, de

Fibre-optic biosensors were constructed for determination of hypoxanthine and xanthine. Xanthine oxidase and peroxidase were immobilized on different preactivated membranes which were subsequently mounted onto the tip of a fibre-optic bundle. The H2O
