This research aims explore prospective utilization inhibitory...
In this work, we report the synthesis of two Schiff bases substituted gallic acid derivatives via amidation reaction and their characterization using 1H-NMR spectroscopy to study inhibition performance on aggressive attack HCl mild steel (MS). The inhibitive was examined chemical (weight loss) electrochemical (Tafel EIS) test methods. results indicate that these significantly suppress dissolution rate adsorption phenomena, which correlates Langmuir model. Tafel data display mixed-type...
Improving oil production for high-salinity reservoirs using polymer flooding is challenging due to chemical and mechanical degradations. This study developed two biodegradable biopolymers based on graft copolymerization of guar gum (GG) with different co-monomers, which are acrylamide (Am) 2-acrylamido-2-methylpropane sulfonic acid (AMPS), cross-linked by N,N′-methylene bisacrylamide (MBA) face these challenges. The newly synthesized gum-based hydrogels, GG-g-poly(Am-AMPS) (GH)...
