A B S T R A C TTwo separate predictive models were developed for optimization and modeling of the relative permeate flux decline (J/J 0 ) and Mg ion rejection (%) in nanofiltration (NF) of oily wastewater. Response surface methodology based on central composite design was employed to experimental design and a cumulative study of the effects of various operating parameters such as trans-membrane pressure (TMP), feed flow rate (Q L ), oil concentration (C oil ), ion concentration (C Mg ), and pH on the NF separation process. Analysis of variance for developed quadratic models exhibited high significance and applicability. The oil and ion concentrations were the most significant factors and their interaction had a prominent effect on both permeate flux and Mg ion rejection. The effect of feed flow rate on the performance was also found to be negligible. The maximum relative permeate flux of 0.86 representing minimum membrane fouling phenomenon was obtained at low levels of input parameters at TMp = 3.4 bar, C oil = 200 mg/L, C Mg = 40 mg/L, and pH 4. Whereas, high rejections were found at high levels of input factors.

“…Traditional methods that have been used for heavy metal removal from aqueous systems include gravimetric processes based upon chemical precipitation and flocculation, solvent extraction, ion-exchange, ultrafiltration, and adsorption [17][18][19]. For analytical applications the traditional laboratory methods of liquid-liquid extraction (LLE) and solid-phase extraction (SPE) have been the dominant methods.…”

In this mini review, recent trends and challenges in developing carbon nanotube-based extraction and electrochemical detection of heavy metals in water are reviewed. Carbon nanotubes (CNT) have electrical, mechanical, chemical, and structural properties superior to those of conventional materials, for example graphite and activated carbon. CNT-based procedures are also more efficient than traditional techniques and methods, for example liquid-liquid extraction, atomicabsorption spectroscopy, flame photometry, and inductively coupled plasma, because they can enable rapid, sensitive, simple, and low-cost on-site detection. Different forms of CNT, including as-grown, oxidised, and functionalised CNT, can be well suited to metal adsorption. The measurement procedure relies on adsorbing the metal on the CNT surface after reasonable contact time, either by applying an electrical potential or under open-circuit conditions, and subsequent quantification. Different types of CNT-based electrode, including composite, paste, and binderfree, can be fabricated and used for metal detection. Application of CNT and their novel properties to the adsorption and detection of heavy metals is discussed in detail.
