摘要: Abstract A series of some new nanomeric molecules cyclic 5- methoxy -5, 6–diaryl -4,5-dihydro -2H-1,2,4–triazin -3-thiones (1-3) has been synthesized. The interaction compounds 1-3 with HgCl2 in 1:1 and 1:2 molar ratios was used for the synthesis macrocyclic Schiff base [5,6, 11,12 - tetraaryl -1,2,4,7,8,10- hexa-aza cyclododoeca -4,6,10,12- tetraene -3,9-dithione] (4), thioethers 5 and/or complex 6. Chemical structures were determined from elemental analysis spectral measurements. screened as molluscicidal agents against Biomophalaria Alexandrina Snails which cause Bilhariziasis. Cyclic voltammetry selected showed well-defined irreversible electrode couple suggesting application these chelating separation arsenic industrial wastewater samples. Compound 1 physically immobilized onto polyurethane foams (PUFs) successfully complete removal (III) & (V) species wastewater.
