Ince, Muharrem; Ince, Olcay Kaplan; Asam, Eren; Önal, Ali
The present study investigated Cu(II) ion adsorption onto banana peel, chestnut shell, and tea leaf waste in aqueous medium under different experimental conditions. Batch adsorption studies were carried out with various Cu(II) concentrations as well as the influence of process parameters such as pH, contact time, and adsorbent amount on the removal of copper, and the optimum conditions for maximum removal of copper from an aqueous solution. These food waste biomass adsorbents were applied to mineral water and industrial wastewater samples and the copper removal potentials were compared. The nature of the adsorbents and metal ion interactions was examined by the fourier transform infrared spectroscopy (FTIR) technique. The adsorption data were obtained by using the Langmuir model showing maximum adsorption capacity of banana peel, chestnut shell, and tea leaf waste at 1.94 mg g-1 2.25 mg g-1, and 3.36 mg g-1, respectively. Copper was determined by flame atomic absorption spectrometry.

Asbestos is dangerous for health and is forbidden to use in Turkey, but villagers who live in rural eastern part still use it especially for their home for insulation purposes and even as a substitute for baby powder. Therefore, geological and chemical properties of this type of soil, which is near the settlement, should be characterized and identified from the point of view of health. Beypinari asbestos deposits are located at Beypinari village, about 90 km southeast of Sivas, Turkey within Central Anatolian Ophiolites. Therefore, in the present study, the existence of chrysotile in Beypinari asbestos deposit were characterized and identified by mineralogical analysis and by major, trace, REE analysis. The results show that the samples contain different amount of calcite mineral, the main mineral being chrysotile.
