Treatment of Crystal Violet from Synthetic Solution Using Membranes Doped with Natural Fruit Extract

Abstract

Innovative polymer membranes with and without natural fruit extract (rosehip) are characterized in terms of their ability of treating a solution containing Crystal violet by a three‐compartment laboratory scale electro‐dialysis cell. Electro‐dialysis is performed at different time intervals and using a constant voltage of 15 V. The dye removal percentage (%) and energy consumption are calculated. The highest value of dye removal is obtained for 90 min (>96%) for membranes doped with natural fruit extract. Water uptake is also determined for the prepared membranes. The physical and chemical properties of the final membranes are investigated by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and thermal gravimetric analysis‐differential scanning calorimetry (TGA‐DSC). FTIR spectra indicated no significant modifications of membrane structure due to the small amount of natural fruit extract. The surface morphology shows that the prepared membranes doped with natural fruit extract is more dense and compact. TGA results shows that the prepared membranes are stable up to 330 °C.

Study of Polyvinyl Alcohol-SiO2 Nanoparticles Polymeric Membrane in Wastewater Treatment Containing Zinc Ions

“…Demineralization rate (D r ) was calculated using the following Equation (1) [ 20 , 35 ]: where λ i and λ f are the conductivities of the initial wastewater and of the final solutions from middle compartment, after 1 h of treatment (mS cm −1 ).…”

“…At the final of the electrodialysis process with three compartments, as a result of the transport process, the solution from the central compartment will be diluted in pollutants, and the solution from the anodic compartment will be enriched/concentrated in pollutants [ 14 , 17 , 18 , 19 ]. Electrodialysis has been successfully applied at the laboratory scale and at the industrial level for treated waters and wastewaters containing contaminants and products, such as: heavy metal ions [ 14 , 17 , 18 ], acids [ 19 ], dyes [ 16 , 20 ], and organic matter [ 16 , 19 ]. The wastewaters may come from different industries, such as: chemistry [ 18 , 19 , 20 ], (bio)chemistry [ 21 ], food processing [ 22 ], pharmaceutical [ 18 , 21 ], mining and refining [ 15 , 17 , 22 , 23 ].…”

Electrochemical Degradation of Crystal Violet Using Ti/Pt/SnO2 Electrode

“…In this work, we were interested in the study of the dye crystal violet (CV) belonging to the family of cationic (basic) dyes. CV is an organic compound of the raw formula C 25 N 3 H 30 Cl (Figure 1) soluble in water, with a molar mass equals to 407.979 g mol −1 , it is widely used as dye for food and textile industry [6,[42][43][44][45][46]. CV was chosen as dye model for its high solubility and its absorbance by UV/Vis spectrometry.…”
