In this study, the removal of color, chemical oxygen demand (COD) and aromatic group from one of the azo dyes, Remazol Yellow RR Gran, had been carried out by using one of the white rot fungi, Phanerochaete chrysosporium. Experimental studies were performed in growth media containing different amounts of dye and glucose. Color measurements were done at 436nm wavelength using spectrophotometer w...

The antimicrobial activity of silver nanoparticles with the clinically important microbes is a major area of research in the field of nanobiotechnology. Syzgium cumini (L.) is used as medicinal plant for anti-diabetic property. The leaves and bark are used for controlling blood pressure and gingivitis. In this present study, we have synthesized silver nanoparticles using Syzygium cumini leaf ex...

Generally, more sophisticated techniques such as, flame atomic absorption (AAS), inductively coupled plasma spectrometer (ICP-MS), and UV/Visible Spectrophotometer were used to determine trace iron metals in pickling (acid cleaning), passivating stainless steel solutions. Simple novel spectrophotometric methods are described for simultaneous determination of iron. While these provide excellent ...

There are specifi c benefi ts to using a UV-Vis spectrophotometer with diode array detector technology compared to those offered when using traditional scanning UV-Vis instruments. Within the molecular spectroscopy group, Agilent is able to offer both types of UV-Vis instruments. The Agilent Cary 60 UV-Vis, based on Xenon fl ash lamp technology, is the ideal scanning instrument for many routine...

PURPOSE To determine the UV absorbance of the corneal layers (epithelium, Bowman layer, stroma) in the 240- to 400-nm range. METHODS Consecutive slices (100 microm) of human cadaveric corneas were cut, and the UV absorbance of each sample was determined in a scanning spectrophotometer. In some cases the epithelium was scraped off and its absorbance measured separately. RESULTS The investiga...

A new in-vitro SPF test method for determining the efficacy of sun care products was proposed and evaluated. The test method is based on UV (Ultra Violet) dosage cumulate response using Gafchromic EBT3 film. In-vitro SPF value of 2 sunscreen standards and 15 commercial products, including sunscreen lotions, BB creams, foundations and sprays with organic and/or inorganic UV filters, were measure...
