Nanoadsorbents for pollutants removal: A review

The potential of nanomaterials as nanoadsorbents and their many advances are discussed in details in this review article. Adsorption is one of the most promising techniques applied for the decontamination of wastewaters from dyes and heavy metals. Nanomaterials possess a series of unique physical and chemical properties. A very important one is that most of the atoms that have high chemical activity and adsorption capacity are on the surface of the nanomaterials. Various nanoadsorbents were elsewhere overviewed in treating contaminated water; their advantages and drawbacks in such applications were evaluated. The implications of nanoadsorbents to public health and their way forward for facilitating environmental sustainability were also discussed.
