Abstract
The rapid and continuous progress in trace analysis of metals is associated with development of several new techniques such as spectrophotometry. Thiosemicarbazones have been used as chromogenic re...

The presence of small quantities of zinc is essential for the growth of plants and animals including human beings
Zinc is one of the more abundant metals in the human body and is vital for the growth, development, where over 300 enzymes contain zinc ions in their active sites (Wałęsa-Chorab et al, 2011). It plays a number of important biological roles such as in the synthesis of deoxyribonucleic acid (DNA) and ribosomal ribonucleic acid (RRNA) (Islam & Ahmed, 2013; Sarma, Kumar, Reddy, Thriveni, & Reddy, 2006)
The deficiency of zinc leads to retarded growth, lower feed efficiency, impaired DNA synthesis, delayed wound healing, decrease in collagen synthesis, and inhibits the general well-being (Krishna Reddy, Rajesh Kumar, Subramanyam Sarma, & Varada Reddy, 2002; Sarma et al, 2006)
Summary
The presence of small quantities of zinc is essential for the growth of plants and animals including human beings. Zinc is one of the more abundant metals in the human body and is vital for the growth, development, where over 300 enzymes contain zinc ions in their active sites (Wałęsa-Chorab et al, 2011) It plays a number of important biological roles such as in the synthesis of deoxyribonucleic acid (DNA) and ribosomal ribonucleic acid (RRNA) (Islam & Ahmed, 2013; Sarma, Kumar, Reddy, Thriveni, & Reddy, 2006). Thiosemicarbazone derivatives are of considerable interest due to their versatility as ligands bearing suitable donor atoms for coordination to metals with strong coordinating ability (Singh & Singh, 2015) They show a wide range of chemical properties depending on the parent aldehyde or ketone (Kovala-Demertzi, Gangadharmath, Demertzis, & Sanakis, 2005; Prathima, Subba Rao, Adinarayana Reddy, Reddy, & Varada Reddy, 2010). The method was applied to soil and vegetable samples as well and compared to standard method flame atomic absorption spectrometry (F-AAS)
