Abstract | ||||
ABSTRACT Nano-Hydroxyapatite (HAp) - polyvinyl alcohol (PVAL) gel was synthesized under pH control. The polyvinyl alcohol was used as the organic carrier for precursor ceramic gel. The ability of the formed hydroxyapatite – polyvinyl alcohol nanocomposite gel for the removal of heavy metals and radioactive nuclides from the environmental calibration standard (ECS) solution was analyzed by inductively coupled plasma mass spectrometer (ICP-MS). The effect of the temperature on the ions removal from ECS solution was studied at various temperatures of 25, 35, 40 ºC. Additionally, the time for complete ions removal was studied between 10 to 45 min. The recorded results showed the success of the gel in complete removal of all ions of the heavy metals and radioactive nuclides after 45 minute of contact with ECS solution at room temperature. | ||||
