“…Besides, curcumin has received considerable attention for its low toxicity and favorable potential in the clinic [24]. Although curcumin acts as an analytical regent, and was used for determining boron [25][26][27], protein [28] and b-cyclodextrin [29], curcumin is hardly used for anion application [30]. Herein, we used curcumin for anion recognition for the first time.…”

“…Spectrophotometric determination of this element has been commonly employed. Spectrophotometric methods based on the usage of different chemicals such as carminic acid [9], curcumin [10], quinalizarine [11] and azomethine-H [12,13] have been applied to determine boron in a varety of matrices. Among all these reagents, azomethine-H has been most widely utilized.…”

Studies on boron, its mechanism and health effects are growing although the safe limits of daily boron exposure have not been clarified. Current knowledge about the toxic levels of boron on humans is not sufficient and needs to be improved. The main toxic effect of boron in animals involves the reproductive system, including specific adverse effects in the male reproductive tract in rats, mice and dogs. Boron determination in biological matrices needs sufficiently sensitive procedures for detection at trace levels, and many techniques do exist. In this paper, we reviewed the general view of potential impact of boron on health, exposure of boron and its determination techniques.

A new differential pulse polarographic (DPP) method has been developed for the trace determination of boron. Its most stable copper complex is used in 0.5 M KNO 3 electrolyte since boron is not electroactive. By continuous addition of tetraborate to copper solution, the copper peak decreased first but then the peak became very small and nearly constant. This point was used for the boron determination. It was found that one mole of copper used two moles of tetraborate. Using this relationship, 1 Â 10 À5 M tetraborate could be determined. The quantification limit was 2.5 Â 10 À6 M and detection limit was 8 Â 10 À7 M. In the presence of complex forming ions such as Pb, Zn, and Cd, the borate found in sample was somewhat smaller because of their reaction with borate. But since their complexes were not as strong as copper, only a few percent of borate were used. No interference was observed in the presence of calcium, chloride and sulfate. This method is applied for the determination of B in borax ore, waste water of borax industries and tap water of Ankara city.
