Abstract

SEVERAL STUDIES HAVE DOCUMENTED THAT PROLONGED EXPOSURE TO HEAVY METALS SUCH AS COPPER, COBALT, ARGENTUMS, NICKEL, ZINC AND LEAD CAN CAUSE DELETERIOUS HEALTH EFFECTS IN HUMANS. THE ABSORPTION OF HEAVY METAL IONS IS A VERY IMPORTANT TOPIC FOR THE DETECTION OF TOXIC METAL IONS IN THE POLLUTED ENVIRONMENTS. NOVEL MULTIDENTATE SILICA-SUPPORTED DIALDEHYDE WERE SYNTHESIZED AND CHARACTERIZED BY ELE-MENTAL ANALYSIS, SOLID PHASE NMR, FT-IR, TG/DTA, SEM AND EDX TECHNIQUES. IN THIS WORK, 0.05 GR OF SILICA-SUPPORTED DIALDEHYDE WAS WEIGHED AND IT ADDED INTO 10 ML OF CATION SOLUTION OF 10-4 MM. THEN, IT WAS PLACED IN THE SHAKER FOR 50 MINUTES. THEN THE MIXTURE WAS POURED INTO A TEST TUBE AND WAS CENTRIFUGED FOR 20 MINUTES AT A SPEED OF 6000 RPM (TO SEPARATE THE ADSORBENT FROM THE SOLUTION). CATIONS THAT WERE STUDIED INCLUDE: COPPER, COBALT, ARGENTUMS, NICKEL, ZINC AND PLUMBUM. AMONG THE CATIONS, SILICA-SUPPORTED DIALDEHYDE WAS HIGHEST ABSORPTION TO AG.FOR DESORPTION OF AG FROM SILICA-SUPPORTED DIALDEHYDE WAS USED FROM NITRIC ACID AND ACID CHLORIDE. BEST DESORPTION WAS ACHIEVED USING HCL.
