Photodegradation of Acid Black 1 and Removing Heavy Metals from the Water by an Inorganic Nanocomposite Synthesized via Simple Co-Precipitation Method

در اين كار آزمايشگاهي، نانوكامپوزيت PbS/ZnS/ZnO با روش هم رسوبي سنتز شد. تاثير نسبت مولي Zn+2 به Pb+2 بر روي مورفولوژي و اندازه محصول بررسي شد. محصول سنتز شده شعه با ميكروسكوپ الكتروني روبشي و اسپكتروسكوپي UV-Vis شناسايي شد. براي بررسي خواص فوتوكاتاليزوري محصول، اسيدبلك1 انتخاب شد. براي بررسي تاثير نانوكامپوزيت سنتز شده بر روي تصفيه آب، از طيف جذبي استفاده شد. نتايج نشان داد كه محصول سنتز شده خواص نوري، فوتوكاتاليستي و تصفيه ي آب خوبي دارد. واژگان كليدي: نانوكامپوزيت، هم رسوبي، خواص نوري، فوتوكاتاليست، تصفيه آب

In this experimental work, PbS/ZnS/ZnO nanocomposite was synthesized via a simple co-precipitation method. Te efect of Zn2+/Pb2+ mole ratio was investigated on the product size and morphology. Te products were characterized via scanning electron microscopy to obtain product size and morphology. Te optical properties of the nanocomposites were studied by ultra violet-visible spectroscopy. Photocatalytic activity of the product was examine by decomposition of acid black 1 as dye. To investigation of the efect of as synthesized nanocomposite on the water treatment, the infuences of the nanocomposite to remove heavy ions was studied by atomic absorption spectroscopy. Te results showed that the synthesized nanocomposite has well optical properties, photocatalytic and water treatment activities.
