Özet:

 In this study, a new thiocyanate-selective solid-contact nanocomposite electrode was prepared by using dichlorobismethyldiphenylphosphine palladiumII complex as ionophore. The optimum composition exhibiting the best performance characteristics of this electrode, constructed by adding some metal oxide nanoparticles to the carbon paste composition, was found as 11.6  graphite powder, 34.8  ionophore, 13.0  o-nitrophenyl octylether o-NPOE, 31.9  tetraheptylammonium tetraphenylborate THATFB and 8.7  cobalt oxide nanoparticles Co3O4 NP. The linear range, the slope, the lifetime, the detection limit, and the response time of the nanocomposite electrode are 1.010-1 - 1.010-6 moldm-3, 59.70.6 mVpSCN, at least 2 months, 1.410-8 moldm-3 and 5 s, respectively. Furthermore, the order of the selectivity coefficients calculated by the separate solution method in the presence of other anions at pH 4.0 was found as carbonate salicylate perchlorate iodide chloride nitrate nitrite sulfite bromide acetate fluoride. It was shown to be a well-functioning indicator electrode for the quantification of thiocyanate in a veterinary drug sample.

 Bu çalışmada, iyonofor olan diklorobismetildifenilfosfinpaladyumII kompleksinin kullanıldığı yeni bir tiyosiyanat-seçici katı-temaslı nanokompozit elektrot hazırlandı. Bazı metal oksit nanopartiküllerinin karbon pasta bileşimine eklenmesiyle hazırlanan bu elektrodun en iyi performans özelliklerinin sergilendiği optimum bileşim  11,6 grafit tozu,  34,8 iyonofor,  13,0 o-nitrofenil oktileter o-NPOE,  31,9 tetraheptilamonyum tetrafenilborat THATFB ve  8,7 kobalt oksit nanopartikülleri Co3O4 NP olarak bulundu. Nanokompozit elektrodun çalışma aralığı, eğimi, kullanım ömrü, alt tayin sınırı ve cevap süresi sırasıyla 1,010-1-1,010-6 moldm-3, 59,70,6 mVpSCN, en az 2 ay, 1,410-8 moldm-3, 5 sdir. Ayrıca, farklı anyonların varlığında pH 4,0da ayrı çözelti yöntemiyle hesaplanan seçicilik katsayılarının sırası karbonat salisilat perklorat iyodür klorür nitrat nitrit sülfit bromür asetat florür olarak bulundu. Tiyosiyanat tayini için iyi çalışan bir indikatör elektrot olduğu bir veteriner ilaç numunesinde gösterildi.
