The current study examines the feasibility of recycling artificially polluted wastewater that contains crystal violet (CV) organic dye by using Azadirachta indica sawdust (AISD) waste as a highly cost-effective adsorbent. Different analytical techniques, viz., SEM/EDX, TEM/SAED, BET, XRD, TGA-DTG, point zero charge (pHpzc), and FTIR, were used to characterize Studies batch adsorption performed ...

The possible utilization of rice husk activated carbon as an adsorbent for the removal of methylene blue dye from aqueous solutions has been investigated. In this study, activated carbons, prepared from low-cost rice husk by sulfuric acid and zinc chloride activation, were used as the adsorbent for the removal of methylene blue, a basic dye, from aqueous solutions. Effects of various experiment...

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 ...

PURPOSE To investigate the retinal toxicity by electroretinography (ERG), clinical examination and histology after intravitreal injection of biological stains in two concentrations: Trisodium (0.50 g/L and 1.00 g/L), Orangell (0.25 g/L and 1.00 g/L) and Methyl Violet (0.50 g/L and 1.00 g/L). METHODS Eighteen New-Zealand albinos rabbits were assigned in six groups (n = 3 in each group). The an...

This study was investigation employed the batch adsorption method using Bardakçı Clay/Van as an adsorbent to remove crystal violent, a cationic dye from aqueous solution. The effects of pH, amount, interaction time and concentration were investigated determine optimal conditions. conditions determined be pH=6, 0.6 g reached equilibrium at 25th minute. isotherm Langmuir, Freundlich Dubinin–Radus...

Adsorption of cationic dye crystal violet (CV) onto a modified walnut shell (WS) adsorbent was investigated. Combined treatment WS using urea and sodium dodecylsulfate (SDS) carried out. Surface modification adsorbents confirmed by FTIR analysis, pHpzc measurements, elemental SEM-EDX analysis. In order to optimize the adsorption conditions, effect solution pH, dose CV concentration studied mean...

This research examined the production of a V2O5-g-C3N4 nanocomposite to remove organic dyes from wastewater. To generate nanocomposite, sonication method was applied. The testing with various (basic fuchsin (BF), malachite green (MG), crystal violet (CV), Congo red (CR), and methyl orange (MO)) revealed that has high adsorption ability towards BF, MG, CV, CR in comparison MO dye. It established...

Toxic cationic dyes are used in different textile industries. When the colour interacts with sunlight, it causes incomplete photosynthesis, inhibiting aquatic organisms’ growth and disrupting gas permeability water system. In this work, carbon nanotubes (CNTs) were prepared to employ acetylene hydrogen as precursor gases a microwave-assisted reactor. The obtained CNTs tested for their ability r...
