Plant wastes including the residues of medicinal plants have recently become one of the major environmental problems in some countries. Zinc sulfide nanoparticles with crystalline structure were synthesized well with the help of green synthesis method by using the residues of medicinal plant Moshgak (Ducrosia Anethifolia). The N-H, –C-O, –C=O, sulfide (S2-), –C-H and phenolic groups existing in Moshgak are responsible and involve for the stabilization of Zn2+ and the formation of Zn-S bond. XRD patterns and SEM images verified the cubic structure of ZnS nanoparticles. The FTIR studies confirmed that –C-O, –C-N, –C-H, –N-H, –N-S and –S-O groups of Moshgak could bind to ZnS nanoparticles. The results of this work demonstrated synthesis of zinc sulfide nanoparticles by using the wastes of Moshgak can be a good alternative for chemical synthesis methods.
