Abstract Due to large specific surface area, abundant functional groups and low cost, biochar is widely used for pollutant removal. The adsorption performance of related synthesis parameters. But the influence factor numerous, traditional experimental enumeration powerless. In recent years, machine learning has been gradually employed biochar, but there no comprehensive review on whole process ...

In this review, adsorbents used in wastewater treatment and their technical feasibilities are reviewed. Adsorbents are classified as natural adsorbents, and the adsorbents obtained from industrial and agricultural wastes. They all were compared with each other condensing the metal binding capacities, costs and metal removal performances in waste water treatments. Although commercial activated c...

In apparent, the intension is removal of chromium using cow dung as low cost adsorbents from the industrial wastewater. Chromium (Cr) is one of the most toxic substances and is introduced into the environment through a variety of industrial activities. In order to remove the chromium from the contaminated water there are lot of methods available, even though they are not in natural way. In the ...

Agro-industrial waste, due to its advantage over other materials, such as abundant disposal, renewable characteristic and low cost, has been arousing interest an option in the production of alternative adsorbents.

Spent tea leaves (STL), a solid waste that is available in large amounts worldwide, was investigated as a potential low-cost adsorbent for the removal of two azo dyes, Reactive Green 19 (RG19) and Reactive Violet 5 (RV5), from contaminated waters. Preliminary experiments conducted on untreated STL showed that this material exhibited very low removal efficiencies (<10 %). By contrast, thermal ac...

The chemical contamination of water from a wide range of toxic derivatives, in particular heavy metals, aromatic molecules and dyes, is a serious environmental problem owing to their potential human toxicity. Therefore, there is a need to develop technologies that can remove toxic pollutants found in wastewaters. Among all the treatments proposed, adsorption is one of the more popular methods f...

A novel, simple and efficient strategy for fabricating a magnetic metal-organic framework (MOF) as sorbent to remove organic compounds from simulated water samples is presented and tested for removal of methylene blue (MB) as an example. The novel adsorbents combine advantages of MOFs and magnetic nanoparticles and possess large capacity, low cost, rapid removal and easy separation of the solid...

In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent types and chemical treatments are proved to have effective roles on the adsorption of Sr(II) ion. Among the three adsorbents, almond green hull demonstrated strong affinity...

Abstract In recent years, the treatment of dye wastewater has attracted more attention because its harmful impact on environment. Therefore, should be treated using effective methods, such as adsorption, which is widely employed to remediate many dyes from wastewater. This work studied use Laurus Nobilis Leaves (LNL) and sawdust (SD) low-cost natural adsorbents reactive blue (RB) synthetic unde...

Abstract In this work, the potential adsorption abilities of mineral materials such as zeolite (Ze), halloysite (Ha), chalcedonite (Ch), and Devonian sand (DS) used low-cost resources for removal Rhodamine B (RhB) from aqueous solutions were investigated in batch conditions. Adsorption kinetics equilibrium effect solution reaction (pH) studied. kinetic data analyzed using two models: pseudo-fir...
