Opis:: The sorption of 241Am3+, 85Sr2+ and 137Cs+ by calcium, strontium and barium alginates has been studied under different operation conditions. The most prominent adsorption was found in the pH range of 5–6 for all systems, even if the observed dependence on the acidity of the solution was small. The most favourable time for the adsorption process was found to be about 2 h for calcium alginate and 4 h for the other two sorbents.

Opis:: Alginates are salts of alginic acid, natural polymers and polysaccharides. They are usually obtained from marine algae. Their solutions often take the form of a gel. The first references to alginates appeared in 1881, so over the years these compounds have been thoroughly studied. Alginates have a lot of valuable properties, which is why they are used in many industries, from stabilizers in the food industry through additives for wound dressings to substances used in bone and muscle regeneration in medicine.

Opis:: The effect of pH on copper ions sorption by alginates has been investigated. The granules of the sorbent obtained from sodium alginate (type DMF, manufactured by KELCO) have been applied. By using a new method of gelation a biosorbent containing from 11.3 to 20.3% mas. of alginate has been produced. Investigations have been carried out at a constant temperature of 25°C and the pH values ranging from 3 to 5. The obtained experimental results have been described by the Langmuir equation. It has been found that with the increasing pH of the solution the maximum biosorbent sorption capacity increased.
