Theoretical study of the adsorption of sodium salicylate and metronidazole on the PANi

Investigating the Adsorption Behavior of Polyaniline and Its Clay Nanocomposite towards Ammonia Gas

“…As noted in the figures, separation of clay layers and formation of PANI inside the clay gallery were achieved. The characteristics of SCCO 2, such as its ability to swell and zero surface tension, selectivity facilitated the penetration of monomers inside the clay layers, to be oxidized by KPS to form PANI chains on and within clay layers [ 5 ]. The TEM image ( Figure 2 D) clarifies that the PANI formed within the clay layer using SCCO 2 (10 MPa) was a nanorod structure, with an average diameter about 60 nm.…”

“…It was noticed that the adsorption capacities varied depending on several factors, mainly the preparation techniques. Recently, PANI and its nanocomposites have been synthesized through several methods and then used as adsorbents for the adsorption of aqueous contaminants, such as Mordant Black 11 dye, methyl red dye, sodium salicylate and metronidazole, and drug contaminants [ 3 , 4 , 5 , 6 ]. Additionally, its electrical and optical properties largely contributed to its utilization in gas sensing applications.…”

Photocatalytic oxidation of pollutants in gas-phase via Ag3PO4-based semiconductor photocatalysts: Recent progress, new trends, and future perspectives

“…Currently, soil, aquatic, and air environment are severely affected by rapid population expansion and the industrial revolution. As we know, there are a wide variety of pollutants annually entering into the natural environment (Aarab et al, 2020a(Aarab et al, , 2020bAbdellaoui et al, 2021;Ajmal et al, 2018;Ba Mohammed et al, 2020;Essekri et al, 2020;Hsini et al, 2020aHsini et al, , 2020bQadeer et al, 2020Qadeer et al, , 2019. The typical indoor air pollutants are generally volatile organic compounds (VOCs), particulate matter (PM), and inorganic oxides (CO2, NOx, and SOx).…”

Synthesis and characterization of arginine-doped heliotrope leaves with high clean-up capacity for crystal violet dye from aqueous media

“…The advancement of a viable economic method of waste management for the coloring industry has long been essential for protecting the environment. In order to clean wastewater and eliminate dyes, numerous treatment approaches have been employed, like photodegradation (Ait Ahsaine et al 2018;Naciri et al 2018Naciri et al , 2019aNaciri et al , 2019bNaciri et al , 2020aNaciri et al , 2020bNaciri et al , 2021Chennah et al 2019;Erdogan et al 2019;Shaim et al 2019;Barebita et al 2020;Bouziani et al 2020Bouziani et al , 2021Akhsassi et al 2021;Mimouni et al 2021), biological oxidation (Paz et al 2017;Sathishkumar et al 2019), nanofiltration membranes (Saffaj et al 2005), ozonation (Oguz et al 2005;Gharbani et al 2008), and adsorption (Kizito et al 2017a(Kizito et al , 2017bAjmal et al 2018Ajmal et al , 2020aAjmal et al , 2020bAarab et al 2020aAarab et al , 2020bBa Mohammed et al 2020). The latter is enhanced compared to other wastewater treatment methods in terms of its preliminary expense, flexibility, easiness of layout, ease of function, and insensitivity toward toxic pollutants (Benafqir et al 2019;Hsini et al 2020aHsini et al , 2021aHsini et al , 2021b.…”
