“…[21][22][23][24][25][26][27][28] Various sophisticated methods are being used for the estimation of aluminum in water and biological samples at concentration levels ranging from the ppm to the sub-ppb levels. [29][30][31][32][33][34][35][36][37][38] It is also interesting that the role of citric acid in forming a complex with aluminum under biological conditions has also been studied. 39,40 The relationship between the concentration of aluminum and poly carboxylic acids, such as tartaric, oxalic, and citric acids, in the rhizosphere and nonrhizosphere of rice soil solution is reported.…”
The coordinating nature of the hydroxy carboxylic acids, such as tartaric and citric acids, has been utilized for the in-situ formation of anions representing the trivalent elements boron and aluminum and two dianions of the hydroxy acid selected under negative electrospray ionization mass spectral conditions. The abundance of these ions could be used for the quantification of boron and aluminum in water at concentrations ranging from 4.0 ppb to 535.0 ppb. For a period of six months, the validity of this method was tested with citric acid as the coordinating agent. Thus, the developed method offers a simple means for the quantification of boron and aluminum in water by negative electrospray ionization mass spectrometry with a single quadrupole mass spectrometer.

Bismuth oxide (Bi2O3) nanoparticles were synthesized using chemical reduction method. The prepared nanoparticles were characterized by Ultra violet – Visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), Fourier Transform Infra-red (FTIR) spectroscopy , Scanning electron microscopy (SEM) and Energy dispersive X-ray (EDX) techniques The characterized nanoparticles were applied as photo catalyst for the degradation of hazardous dye Xylene Cyanol FF in aqueous medium. The effects of different parameters such as irradiation time, initial dye concentration, catalyst dosage, pH of the medium and temperature were studied on the photo catalytic degradation of the dye. It was found that with increase in irradiation time and catalyst dosage the degradation exponentially increased and decreased with increase in initial concentration of the dye. The temperature was found to have no appreciable effect on the dye degradation in open atmosphere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
