Electrochemical behaviour of metal complexes of salicylic acid hydrazide

Abstract

The present article deals with the electrochemical investigations of salicylic acid hydrazide SAH and its complexes of cadmium II , copper II , manganese II , nickel II , zinc II , cobalt III and iron III . The results obtained in polarography are compared with that in cyclic voltammetric studies. The effect of height of the mercury column on wave height, the effect of concentration of the complex on the wave height and half wave potential and the effect of temperature etc were studied in detail and the sites susceptible for reduction were explored and presented.

Abstract

S unulan çalışma, salisilik asit hidrazürün SAH ve kadmiyum II , bakır II , mangan II , nikel II , çinko II , kobalt III ve demir III komplekslerinin elektrokimyasal incelenmesini içermektedir. Polarografiden elde edilen sonuçlar, dönüşümlü voltametre sonuçlarıyla karşılaştırılmıştır. Civa kolon yüksekliğinin dalga yüksekliğine etkisi; kompleks derişiminin dalga yüksekliğine ve yarı-dalga potansiyeline etkisi ve sıcaklığın etkisi vb. değişkenler ayrıntılı olarak incelenmiş ve indirgenme bölge duyarlılığı sunulmuştur
