background; dyes can cause many problems in environment. therefore, removal of these contaminants before discharging wastewater to environment can reduce the environmental hazards. adsorption is one of the usual processes for decolorizing from wastewater. nanotubes are new adsorbents that can adsorb different compounds. this work aimed to investigate acid violet 17 dye removal by adsorption usi...

Intercalation imparts interesting features to the host graphite material. Two different types of intercalated compounds called (GIC-bisulphate or Nyex 1000 and GIC-nitrate or Nyex 3000) were tested for their adsorption capacity and ability to undergo electrochemical regeneration. It was found that Nyex 3000 showed comparatively slow kinetics along with reduced adsorption capacity to one half fo...

Results with two ultramicro methods for plasma uric acid analysis with uricase are described: a crystal violet (gentian violet) method, modified from an automated procedure by Gochman and Schmitz [C/in. Chem. 17, 1154 (1971)] and adapted to manual analysis, and a polarographic oxygen-sensing system (Beckman Instruments,Inc.).The coefficientof variation (CV) for the crystal violet method varied ...

violet is one of the ornamental plants with a good value in landscaping and herbal medicine. salicylic acid is a signaling agent involving in secondary metabolite production. the aim of this study was to evaluate the physiological responses of violet flowers to exogenous salicylic acid. this experiment was conducted in the greenhouse, as a completely randomized design. salicylic acid was spraye...

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) ...
