Abstract Crystal Violet dye is a toxic organic pigment that has little solubility in water and causes serious health problems environmental pollution. In the current study, compound composed of multi-walled carbon nanotubes with chitosan was used. Experiments were conducted to adsorb crystal violet for both effect surface weight adsorbent contact time. Dye CS-OMWCNTs. And study pH ionic intensi...

A sensitive and selective amperometric sensing platform for lead (Pb(2+)) was developed based on a Pb(2+)-induced G-rich DNA conformational switch from a random-coil to G-quadruplex (G4) with crystal violet as the G4-binding indicator.

The first application of crystal violet as a selective fluorescent switch-on probe for i-motif DNA has been reported. This interaction has been exploited to develop a label-free DNA-based "OR" logic gate for potassium and hydrogen ions.

Herein, we report the performance of some low-cost biosorbents developed by environment-friendly modification walnut shells. Two types were prepared ecological shell surfaces: (1) obtained hot water treatment (WSH2O) and (2) produced mercerization (WSNaOH). Different techniques used to evaluate morphological, elemental, structural biosorbents, comparison with raw materials. These characterizati...

The economic viability of adsorbing crystal violet (CV) using pepper seed spent (PSS) as a biosorbent in an aqueous solution has been studied. A parametrical investigation was conducted considering parameters like initial concentration dye, time contact, pH value, and temperature variation. analysis experimental data obtained carried out by evaluating with the isotherms Freundlich, Sips, Tempki...
