“…To overcome limitations associated with conventional water treatment systems, a new adsorption technique based on the application of carbon nanotubes (CNTs) has been introduced [21]. CNT-based nanofiltration membranes allow for refinement and optimization of all membrane aspects, such as small and uniformed pore sizes as well as precise control of membrane reactivity.…”

In the past few years, there is impressive breakthrough for the research on nano structured materials to solve global significant challenges like, water, energy, environment, medicine etc. Among various nanomaterials, carbon nanomaterials (CNMs) are gaining significant interest to the material scientists to develop advanced membranes for novel separation processes. It is believed that CNM based membranes have the potential to overcome the inherent limitations of conventional membranes separations.

“…Nanotubes are characterized by excellent mechanical, thermal and electrical properties [Saito et al 1998], which result from their length-to-diameter ratio, surface smoothness and hydrophobicity [Noy et al 2007, Kar et al 2012]. These properties allow the use of nanotubes in the production of unique composites, including polyacrylonitrile composites [Palade et al 2015].…”

This paper presents the results of research on the production of composite polyacrylonitrile (PAN) membranes with nanotubes (MWCNT), graphene (RG) and graphene oxide (GO) addition. All of the specified additions differ diametrically in terms of properties, starting from the spatial structure of the particles, to the chemical properties. The membranes were obtained using phase inversion method from a solution of N,N-dimethylformamide (DMF). Subsequently, the impact of the nano-addition on the transport and separation properties of the membranes was investigated using Millipore AMICON ultrafiltration kit. Membranes with graphene addition (PAN/RG) are characterized by the best transport properties and the highest specific permeate flux values in the range of ~913÷1006 dm 3 /m 2 ×h for the working pressure of 2.0 MPa. In order to test the separation properties, electroplating wastewater generated in one of the Silesian galvanizing plants was used. The qualitative and quantitative composition of the wastewater was tested by means of UV-Vis spectrophotometer (HACH) and absorption atomic spectrometry (AAS). The ultrafiltration process carried out on composite membranes allows for the complete removal of phosphate ions and ~88÷94% removal of iron from the waste water. The rejection coefficient of the remaining metals is high: ~35÷85% for copper and ~17÷100% for cadmium.
