Removal of Sr (II) Metal Ions from Aqueous Solution by Using Natural Zeolite and It’s Na-Zeolite Derivative

In the present work Stilbite (Natural Zeolite), Na-Zeolite are exchanged with Sr(II) metal ion to study the removal of heavy metal ions from the industrial waste water. The analysis of the present zeolite and exchanged derivative has been carried out using Inductive Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). The exchanged derivative is then used to prepare adsorbed derivatives with Sr(II) metal ion. The structural changes are studied by IR spectroscopy. The exchange percentage of Sr(II) metal ion with natural zeolite is maximum than Na-zeolite. In this study Scan Electron Microscopy (SEM) analysis for morphological structure and XRD technique is used to determine the unit cell structure of synthesized and natural zeolite. Also thermal studies of natural zeolite and its exchanged derivative are carried out using TGA (Thermal Gravimetric Analysis). For the same samples FESEM (Field Emission Scanning Electron Microscope) and EDAX analysis is also carried out. We successfully exchanged Sr(II) metal ions with Stilbite-natural zeolite and doped Na-zeolite.
