Two-Dimensional (2D) Nanomaterials in Separation Science

The environment is continuously threatened with various kind of pollu�tants, which have detrimental effects not only on human health, but also on eco�systems. In general, the water body is an easy route to wastewater disposal where many contaminants of emerging concerns, such as pharmaceuticals and personal care products etc. are present. Very recently, other classes of novel water pollu�tants occur which include nanoplastics and nanoparticles. Here, we discuss both classical and newly emerging water pollutants categories with their possible conse�quences. In addition, treatments and tackling techniques of these water pollutants are summarized. Ten different areas of concern to solve these problems and challenges of emerging water pollutants are highlighte

Emerging Water Pollutants and Wastewater Treatments

The environment is continuously threatened with various kind of pollutants, which have detrimental effects not only on human health, but also on eco-systems.

Very recently, other classes of novel water pollutants occur which include nanoplastics and nanoparticles. Here, we discuss both classical and newly emerging water pollutants categories with their possible consequences.

Novel acid treated biomass: Applications in Cu2+ scavenging, Rhodamine B/Cu2+ binary solution and real textile effluent treatment

A novel adsorbent prepared from the waste of Irvingia gabonensis nut (ADN) was used for scavenging of Cu from aqueous solution. Various adsorption operational parameters were investigated in order to establish the behavior of ADN before further studies. The efficacy of ADN in concurrent removal of rhodamine B (RhB) dye and Cu in a binary solution of RhB/Cu was also investigated. Finally the potency of ADN in the treatment of real textile effluent was ascertained. Optimum adsorption of Cu occurred at pH of 5.5 and high temperature favored Cu removal. Pseudo second order kinetic best described the uptake of Cu onto ADN. Maximum monolayer adsorption capacity was obtained to be 103.09 mg/g. The Dubinin Radushkevich (D-R) isotherm as well as thermodynamic parameter suggests that adsorption of Cu onto ADN was chemical in nature. Percentage removal of Cu in single solution at optimum time was 94.70 % while synergistic effect of RhB moved this to 99.54 % removal in the binary solution. ADN was highly efficient for the removal of dye and other organic pollutants in the real textile effluent with 100 % removal of some organic pollutant
