Background: Nanomaterials offer promising remediation techniques for water containing toxic pollutants especially heavy metals. Methods: A complete analysis of the application of nano-adsorbents for heavy metals removal from water has been reviewed. The effect of their functionalization on the adsorption capacity, the reusability, and the surface area has also been discussed.

Background: Clean and clear water is an essential element in our life. Finding new and innovative approaches to purify water is a critical topic in research and development. Carbon nanotubes are promising adsorbent for many stable organic compounds. The ability of wastewater treatment using carbon nanotubes was studied in this review article. Methods: Adsorption mechanism was discussed based on several

Background: Formation of the microbial colonies in the wet and damp environment affects the indoor air quality thus posing severe threats to human health. Health problems or Building- associated illness (any disease or infection) caused by being in a closed space or building are generally separated into two categories including building-related illness (BRI) and sick building syndrome (SBS). Considered

Background: In the present situation where there is a water shortage globally, nanoparticles can play a vital role in treating wastewater to make it usable for several processes. Industrial wastewater contains numerous heavy metals and associated wastes that enter our food chain by one means or other. This article provides a review of applications of nanoparticles in wastewater treatment and highlights

Background: Cadmium contamination is becoming an important issue globally due to its high toxicity and carcinogenicity, leading to detrimental effects on both environmental and human health. This review paper discusses the different sources of cadmium, its toxic effects on the environment and human health, and the influence of different soil factors in changing the speciation and bioavailability of

Background: The removal of persistent organic pollutants (POPs) from the contaminated water by employing photocatalytic adsorption is considered as one of the most emerging technologies due to its’ cost- and energy-effectiveness. It has attracted significant attention of global researchers to process the world’s wastewater. Methods: Among different adsorbents, the metal-organic frameworks (MOFs) have

Background: Azo dyes are recognized as non-decomposable and recalcitrant compounds and can be depleted into more dangerous secondary products in anaerobic environments. In the current scenario, different water treatment strategies, including adsorption, photocatalysis, and advanced oxidation processes based practices, are facing different limitations. Methods: A literature survey was accomplished by

Background: In the last decade, research in the field of contaminants of emerging concern proliferated while special interest was focused on antibiotic-resistant bacteria, antibiotic resistance genes as widespread pollutants. Advanced oxidation processes have gained an essential attraction in the field of antibiotics degradation and bacteria inactivation Methods: Photocatalysts in the form of sol-gel

Background: Bulk generated textile wastewater loaded with dyes is posing a stern threat to aquatic health, especially when dumped without prior treatment. Lignocellulosic waste based activated carbon (AC) and Titania (TiO2) suspension can constitute the emerging technological solution. Objectives: Best lignocellulosic precursor biomass, Melia azedarach (Darek sawdust - DSD), was selected for ortho-phosphoric
