Advanced Chemical Reduction of Reduced Graphene Oxide and Its Photocatalytic Activity in Degrading Reactive Black 5

Textile industries consume large volumes of water for dye processing, leading to undesirable toxic dyes in water bodies. Dyestuffs are harmful to human health and aquatic life, and such illnesses as cholera, dysentery, hepatitis A, and hinder the photosynthetic activity of aquatic plants. To overcome this environmental problem, the advanced oxidation process is a promising technique to minerali...

Maskless photolithography using UV LEDs.

A UV light emitting diode (LED) with a maximum output of 372 nm was collimated using a pinhole and a small plastic tube and focused using a microscope objective onto a substrate for direct lithographic patterning of the photoresist. Movement of the substrate with a motorised linear stage (syringe pump) allowed lines in SU-8 to be pattered with a width down to 35 microm at a linear velocity of 8...

Fenton oxidation of Reactive Black 5: effect of mixing intensity and reagent addition strategy.

This study investigates the effect of mixing intensity and reagents addition strategy on Fenton's reagent degrading a common reactive diazo type dyestuff, Reactive Black 5. Within the experimental conditions used in the study, the effect of mixing intensity on TOC removal was observed to be both significant and complex. Using factorial analysis, it was found that if the reagents are added near ...

Application of Fenton Oxidation Process for Degradation of Reactive Black 5 in Aqueous System

In the study, Reactive Black 5 (RB5) was removed from synthetic wastewater using Fenton's oxidation (FO) process. Batch experiments were conducted on the samples containing 50, 250 and 500 mg/L of RB5. The study was performed in the systematic optimum value of H2O2 and FeSO4 concentrations, pH and temperature. Optimum pH and temperature for 250 mg/L RB-5 were observed at 3.0 and 40°C respective...
