Journal ArticleDOI
Arsenic removal technologies and future trends: A mini review
Sadiya Alka,Shafinaz Shahir,Norahim Ibrahim,Mohammed Jibrin Ndejiko,Dai-Viet N. Vo,Fazilah Abd Manan +5 more
TL;DR: Arsenic contamination has been widely recognized as one of the most consequential environmental pollutants due to its anthropogenic activities and its associated removal techniques have become the focus of many institutions, including industries, environmental groups, and the general public.
Journal ArticleDOI
Removal of heavy metals from aqueous solution using carbon-based adsorbents: A review
TL;DR: In this article, the effect of process conditions, such as temperature, pH value, and coexisting ions, on adsorption performance are combed, and the universal guidance law is obtained.
Journal ArticleDOI
Adsorption of heavy metal ions by various low-cost adsorbents: a review
TL;DR: In this paper, the authors proposed a method to remove heavy metal ions in the wastewater, which is one of the most serious concerns of the world, in the pursuit of remedial action.

A critical review on arsenic removal from water using biochar-based sorbents: The significance of modification and redox reactions
Rabia Amen,Hamna Bashir,Irshad Bibi,Sabry M. Shaheen,Sabry M. Shaheen,Sabry M. Shaheen,Nabeel Khan Niazi,Nabeel Khan Niazi,Muhammad Shahid,Muhammad Hussain,Vasileios Antoniadis,Muhammad Bilal Shakoor,Samir G. Al-Solaimani,Hailong Wang,Jochen Bundschuh,Jörg Rinklebe,Jörg Rinklebe +16 more
TL;DR: In this article, a review of biochar use as a sorbent for arsenic removal from drinking water, either pristine or modified, is presented, which discusses various factors governing the removal potential of biochars (e.g., pH, biochar dose, physico-chemical properties, fate of sorbed As on biochar, and the redox-mediated interactions between biochar and As).
Journal ArticleDOI
The improved methods of heavy metals removal by biosorbents: A review.
TL;DR: It is thought that intracellular autogenous nanomaterials may open up another window in biosorption of heavy metals area and the combination of various treatment methods will be the development tendency of heavy metal pollution treatment in the future.

A review of the source, behaviour and distribution of arsenic in natural waters
TL;DR: The scale of the problem in terms of population exposed to high As concentrations is greatest in the Bengal Basin with more than 40 million people drinking water containing ‘excessive’ As as mentioned in this paper.
Journal ArticleDOI
Comparison of arsenic(V) and arsenic(III) sorption onto iron oxide minerals: implications for arsenic mobility.
Suvasis Dixit,Janet G. Hering +1 more
TL;DR: The sorption data indicate that, under most of the chemical conditions investigated in this study, reduction of As(V) in the presence of HFO or goethite would have only minor effects on or even decrease its mobility in the environment at near-neutral pH conditions.

Protein release from alginate matrices.
Wayne R. Gombotz,Siow Fong Wee +1 more
TL;DR: By selection of the type of alginate and coating agent, the pore size, degradation rate, and ultimately release kinetics can be controlled.
Journal ArticleDOI
A review on the adsorption of heavy metals by clay minerals, with special focus on the past decade
TL;DR: A detailed review compiles thorough literature of current research over the last ten years (2006-2016) and highlights the key findings of adsorption studies that use clay minerals as an adsorbent.

Recent advances in removing phosphorus from wastewater and its future use as fertilizer (1997-2003).
Luz E. de-Bashan,Yoav Bashan +1 more
TL;DR: This comprehensive review summarizes the current status in phosphorus-removal technologies from the most common approaches, like metal precipitation, constructed wetland systems, adsorption by various microorganisms either in a free state or immobilized in polysaccharide gels, to enhanced biological phosphorus removal using activated sludge systems, and several innovative engineering solutions.
