“…Therefore, the study of new technologies for the treatment of 4NA-contaminated water is a topic of great scientific interest. Several processes have been described for the removal of 4NA from water sources, including biodegradation [ 6 , 7 , 8 , 9 ], oxidation [ 10 ], reduction [ 11 , 12 ], adsorption [ 13 , 14 , 15 ], advanced oxidation processes [ 16 , 17 , 18 , 19 ] and pressure-driven membrane processes [ 20 , 21 ].…”

4-Nitroaniline (4NA) is a common organic pollutant that is released into the environment during the manufacture and processing of a wide variety of industrial products. This article describes the use of an emulsion liquid membrane process to remove 4NA from aqueous solutions using a type 1 facilitated transport mechanism. Optimization of the removal process was carried out by analyzing the efficiency of 4NA removal from the feed phase and the initial apparent feed/membrane fluxes and permeabilities under different experimental conditions. The kinetics of the removal process was analyzed using a simplified mass transfer model involving an empirical mass transfer coefficient calculated from experimental data, assuming that the concentrations of 4NA in the external aqueous phase and in the internal w/o emulsion are uniform. The results show that there is a very good fit between the experimental and model data and that the variation in the values of the overall mass transfer coefficients with the experimental conditions coincides with that of the removal efficiency mentioned above. The transport mechanism was studied by identifying the rate-controlling step of the removal process, using models described for adsorption processes, due to the strong parallelism between the transport mechanisms in adsorption and emulsion liquid membrane processes.

“…Consequently, it is mandatory to remove phenolic compounds from wastewaters before their disposal in the environment (Al-Aoh et al, 2013). Accordingly, some treatment technologies are introduced to remove PNP from aqueous media, including microbiological, reverse osmosis (Hidalgo et al, 2015), photocatalytic, electrochemical oxidation (Zhang et al, 2013) and adsorption (Cotoruelo et al, 2012).…”

Paranitrophenol (PNP) is one of the toxic chemicals, non-degradable, and bioaccumulative. In the present work, the nonlinear analysis method was used to assess the kinetics and equilibrium for PNP adsorption on commercially available Powdered Activated Carbon (PAC) from an aqueous solution. The adsorption kinetic data were analyzed using the Pseudo First Order (PFO), Pseudo Second Order (PSO), and Elovich models. The experimental data were fitted using two-parameter isotherms model (Langmuir, Freundlich and Temkin) and three parameters isotherms model (Sips, Redlich – Peterson and Toth). For the kinetic study, the adsorption process fitted the PSO model. Among two-parameter models, the Freundlich is better described for PNP adsorption on PAC. From three-parameter isotherms, the Sips model was found to be the best representative for PNP adsorption on the PAC. The results of the present study showed the efficiency of using PAC as an adsorbent for the removal of PNP from an aqueous solution.
