Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...

Sol-gel technique was used to coat multiwall carbon nanotubes (MWCNTs) with anatase titania to increasing the surface area and improve the photocatalytic activity of TiO2. Room temperature ballistic conduct of MWCNT combined with semiconducting behavior of anatase brought about a photocatalytic improvement of ~37 % with respect to the highest methyl orange decolorization flair. For characteriza...

In textile industry during the dyeing process roughly 10% of synthetic dyes were used and let into the wastewater. Among all dyestuff Azo dyes occupies in majority, because they are extensively used in the textile, paper, food, leather, cosmetics and pharmaceutical industries. They represent chief polluting components ranging from inorganic compounds to polymers and organic elements. However pr...

The present study focuses on effects of operational parameters on electrochemical wastewater treatment for synthetic wastewater. Electro-oxidation has emerged as one of the advanced oxidation processes gaining more attention because it offers many distinctive advantages over other conventional methods such as versatility, high treatment efficiency, safety, amenability of automation and cost eff...

This work studied the potential use of horseradish peroxidase (HRP) in the decolorization of the following textile dyes: Drimarene Blue X-3LR (DMBLR), Drimarene Blue X-BLN (DMBBLN), Drimarene Rubinol X-3LR (DMR), and Drimarene Blue CL-R (RBBR). Dyes were individually tested in the reaction media containing 120 mg·L(-1), considering the following parameters: temperature (20-45°C), H(2)O(2) conce...

Wheat straws are a globally abundant agro-waste that may play critical role in the global transition from single-use plastics to green materials as an inexpensive and renewable raw material. Vast amounts of wastewater produced during technological process wheat straw-cellulose/hemicellulose conversion. In this context, work focuses on decolorization via activated carbon adsorption. A set carefu...

The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 different fungal species. Several strains exhibi...
