Abstract

Recently Nano-materials were applied   in different  fields as  chemistry, medicine and agriculture. the present work aimed to indicate the   applications of Nano-materials in the voltammetric determination of some compounds also in the removal of pollutants. The nanomaterial's were synthesized using different method viz chemical, mechanical and biological methods  The nano-structure materials were characterized using electron-microscopy (Fig. 1) and X-Ray Diffraction. The prepared materials used to modify carbon paste electrode. modified electrode were widely used for the electrochemical determination of pollutants, metal ions and pharmaceutical compounds. From other hand the prepared materials were used to remove pollutants. From other hand the prepared materials were used to remove pollutants. Through photocatalytic decomposition A detection limit of about 10-10 M was obtained using voltammetric techniques such as linear sweep voltammetry, differential pulse voltammetry and square wave voltammetry. Modification of the carbon paste electrodes increased the surface area and enhance the sensitivity comparing to non-modified electrode. Another application of nanomaterial's is the removal of some pollutants. A removal of  about  80 % from some pollutants was achieved using TiO2 nano particles. The work report different methods for synthesis nano – materials and applications in the field of chemistry.
