| Abstract: | An iodine containing natural zeolitic material of the clinoptilolite type heated to different temperatures was investigated by means of X-ray photoelectron spectroscopy and thermal analysis methods. At room temperature the iodine was found to be present, depending on the preparation conditions, in the form of iodide or iodide combined with elementary iodine. After heating to 200°C, only iodide was observed which persists in the product in a small amount also after heating to 900°C. |
