The inhibitory effect of di-imine-SB namely ((N1Z, N4E)-N1, N4-bis (4 (dimethylamino) benzylidene) butane 1,4-diamine) on X65-steel in 1 M HCl has been investigated experimentally and theoretically. electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), weight loss outcomes display the anticorrosion properties "di-imine- SB". efficiency exceeds 90% at optimal concentration × 10-3 metal surface was examined further using scanning electron microscope (SEM) energy...
Linear alkyl benzene sulfonic acid (L) and three of its ester derivatives (L1, L2, L3) were prepared, followed by quaternization these esters (L1Q, L2Q, L3Q). The corrosion inhibition effect on carbon steel in 1 M HCl was studied using weight loss potentiodynamic polarization measurements. adsorption the inhibitors surface obeyed Langmuir's isotherm. associated activation energy other thermodynamic parameters such as enthalpy (ΔH∗), entropy (ΔS∗) activation, adsorption–desorption equilibrium...
Antidepressants are one of the main pollutants in aquatic environment. They being widely studied due to their widespread use, possible health effects, and partial removal from wastewater treatment plants by conventional methods. Photocatalysis is an effective ecologically beneficial method treatment. In present study, photocatalytic degradation sertraline hydrochloride (SERT) water using nano-sized zinc oxide (ZnO-NPs) was investigated. The ZnO-NPs were synthesized gluconate as a precursor...
The corrosion inhibition process of carbon steel in 1 M HCl by octadecylbenzene sulfonic acid (H) and their three ester derivatives (H1, H2, H3) were studied. esters quaternized n-butyl bromide to get (H1Q, H2Q, H3Q). These products have been investigated as inhibitors using weight loss potentiodynamic polarization measurements. From the obtained results it was found that, efficiency increases with increasing inhibitor concentration ranked (H3Q > H2Q H1Q H3 H2 H1 H). adsorption on surface...
The work explores the synthesis and properties of a novel composite membrane system based on modified polystyrene (PS) grafted onto polyvinyl chloride (PVC) membrane. PVC membranes were prepared by solution-casting followed exposure to an atmospheric pressure dielectric barrier discharge (DBD) with O2 obtain activated surface for grafting PS it. Moreover, thus chemically furthermore amination polyethyleneimine or sulfonation 4 M sulfuric acid. characteristics such as wettability, structure...
This work reports the synthesis and properties of a new membrane based on polyvinyl chloride (PVC) grafting with polyacrylic acid (PAA) using argon (Ar) plasma. The membranes PVC were synthesized by solution-casting method, where PAA was deposited as an ultrathin film onto dielectric barrier discharge at atmospheric pressure Ar gas. surface characteristics chemical composition modified analyzed water contact angle, scanning electron microscopy, Fourier transform infrared spectroscopy....
Abstract Linear and heavy alkyl benzene (HAB) were sulfonated with fuming sulfuric acid (oleum) the products esterified tri poly ethanolamine ( d = 4 6). The prepared three esters from each series quaternized n ‐butyl bromide. resulted six ester of linear HAB sulfonate named as (L1Q, L2Q, L3Q, H1Q, H2Q, H3Q). surface thermodynamic properties these compounds have been investigated. From data obtained, it was found that tension active for derivatives better than which obtained (LAB)...
This work explores the synthesis and properties alteration of new composite membrane system based on polyvinyl chloride (PVC) grafting with polyacrylic acid (PAA) using argon (Ar) plasma. The membranes PVC were synthesized by solution-casting method, where PAA was deposited onto dielectric barrier discharge (DBD) at atmospheric pressure different carrier gases such as (O2, Ar, N2, air) to get optimum condition for process acrylic acid. Physicochemical investigated function varied gas PAA....
