“…These negative charges on the surface of the adsorbent increase, resulting in an increase in repulsion between M-nOG and arsenic. 91 As(III) and As(V) removal is maximum at a temperature of 35 °C as shown in Fig. 6.…”

“…Similar to CNTs, graphene has been combined with metal nanoparticles such as silver, iron oxides and TiO 2 to impart antibacterial, heavy metal ion and organics affinity respectively. An iron oxide/non-oxidative graphene/CNT composite gave a maximum adsorption capacity for As(III) and As(V) as 9.11 and 5.21 mg/g respectively [160]. The removal of over 98% humic acid from water was achieved using a novel TiO 2 nanowire/iron oxide nanoparticle/GO composite, where the iron oxide facilitated humic acid adsorption and the combination of TiO 2 nanowires and GO allowed photocatalytic degradation of the species [185].…”

Abstract:To ensure the availability of clean water for humans into the future, efficient and cost-effective water purification technology will be required. The rapidly decreasing quality of water and the growing global demand for this scarce resource has driven the pursuit of high-performance purification materials, particularly for application as point-of-use devices. This review will introduce the main types of natural and artificial contaminants that are present in water and the challenges associated with their effective removal. The efficiency and performance of recently developed materials for water purification, with a focus on activated carbon, carbon nanotubes and graphene will be discussed. The recent advances in water purification using these materials is reviewed and their applicability as point-of-use water purification systems discussed.

“…Of these technologies, adsorption is the most promising technique due to its cost-effectiveness, ease of operation, and consistent performance. 3,4 Due to large specific surface areas and hollow ability to be combined with metal oxides, carbon nanotubes (CNTs), which are one-dimensional substances, have great potential as superior adsorbents for removing Ni( ii ) ions. 5 However, this adsorbent has the disadvantages of low adsorption capacity or low removal efficiency because of severe aggregations occurring due to the strong van der Waals forces among them.…”
