In the present study, silica aerogel- egg shell was synthesized for dye removal of colored wastewater. The nano composite structure was characterized by Fourier transform infrared spectra FTIR and scanning electron microscope SEM.The ability of nano composite absorption was assessed for removal basic violet 16BV16 dye from aqueous solutions and was compared with two other adsorbents such as egg...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...

Basic Violet 14, Direct Red 28 and Acid Red 26 are classified as carcinogenic dyes in the European textile ecology standard, despite insufficient toxicity data. In this study, the toxicity of these dyes was assessed in a zebrafish model, and the underlying toxic mechanisms were investigated. Basic Violet 14 and Direct Red 28 showed acute toxicity with a LC50 value at 60.63 and 476.84 µg ml(-1) ...

In this paper, the results of studies of the sorption activity of Salvadora Persica fine particles that were provided from internal natural resources at Iran, with respect to Crystal Violet, Basic Violet-16 and Basic Blue-41 dyes were presented. Thus, Salvadora Persica particles were modified and prepared via particle size decreasing and characterized by CHNS, XRD, SEM and FT-IR analysis. In th...

the effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on ethyl violet adsorption was investigated. it was found that surface chemistry plays an important role in ethyl violet (ev) adsorption. hcl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of ev dye. the adsorption efficien...

Article history: Received 16 January 2017 Accepted 16 January 2017 Available online 19 January 2017 hypothesis. We are currently doing a clinical trial Minami Aoyama Eye Clinic in Tokyo, Japan using a violet light-emitting desktop light and violet light-transmitting eyeglasses (Clinical trial number: UMIN000021897). Also, a randomized clinical trial is underway on violet light transmitting eyeg...
