The objective of the review paper aims to explore and provide insight into various low-cost adsorbents prepared and used in the removal of hazardous dye pollutants from the contaminated industrial effluents Background: The major untreated discharge from the textile industries constitutes a wide range of organic contaminants with the enhanced concentration of biological oxygen demand and chemical oxygen d Read More

Background: Rapid industrialisation, population growth and technological race worldwide have brought adverse consequences on water resources and, as a result, affect human health. Toxic metal ions, non-biodegradable dyes, organic pollutants, pesticides, pharmaceuticals are among the chief hazardous materials released into the water bodies from various sources. These hazardous contaminants drastically affect flora an Read More

Background: The occurrence of pharmaceuticals in surface and drinking water is ubiquitous and is a major concern of researchers. These compounds cause a destructive impact on aquatic and terrestrial life forms, and the removal of these compounds from the environment is a challenging issue. Existent conventional wastewater treatment processes are generally inefficacious because of their low degradation ef Read More

Background: Rapid escalation in textile, paper, pesticides, pharmaceuticals and several other chemical-based manufacturing industries due to amplification in human requirements have proportionately contributed to the extreme contamination of the water ecosystem, resulted from the discharge of toxic pollutants from industries. Effluents from textile industries are comprised of coloured dyes like Rhodamine B, Methyl O Read More

Background: The world’s production of whey is estimated to be more than 200 million tons per year. Although whey is an important source of proteins with high nutritional value and biotechnological importance, it is still considered as a by-product of the dairy industry with low economic value due to low industrial exploitation. There are several challenges in the separation of whey proteins: low concentration, the complexi Read More

Background: Cellulose is one of the most abundant, non-toxic, and renewable natural biopolymers. The presence of hydroxyl groups in cellulose leads to further modification of it. Preparation and modification of cellulose-based sorbents and their applications on water treatment gained traction in recent years Objective: A low-cost and eco-friendly biosorbent was designed and fabricated by introducing the acetate functi Read More

Background: Rapid urbanization and industrialization have led to the depletion of water resources and the generation of an enormous amount of wastewater. One among them is the textile industry, which discharges a huge amount of dye wastewater into the aquatic environment. Methods: This study deals with adsorption of Remazol blue, Malachite green and Rhodamine B dyes into bio-char derived from Chlorella Vulgaris bi Read More

Background: With the increasing population and decreased quality of drinking water, new materials and methods for the purification of water need to be developed. This study aims to present a solution from pollution by proposing the synthesis method of sodium lauryl sulphate (SLS)-supported thorium (IV) phosphate (ThP), its characterisation and disquisition of analytical applications by executing dual separations of calcium. Me Read More

Background: The presence of heavy metal contaminants such as chromium, lead, mercury, cadmium, arsenic, nickel, and copper has become a major issue for human health. Chromium is extremely toxic to living organisms as it acts as a carcinogen and mutagen. The high concentration of chromium may cause detrimental effects to human health in the long term. The mutagenic and carcinogenic properties, included Cr(VI) Read More

Background: Removal of lead (II) ions from supply water using an inexpensive adsorbent is essential. It is recommended that low-cost adsorbents are developed to effectively remove lead (II) ions from aqueous solutions. The aim of the study was to develop and validate models for predicting the performance of carboxylated jute stick derived activated carbon (JSAC-COOH) in removing lead (II) ions from aqueous solution, whic Read More
