Efficient Uptake of Angiotensin-Converting Enzyme II Inhibitor Employing Graphene Oxide-Based Magnetic Nanoadsorbents

چکیده
This paper reports a high efficiency uptake of captopril (CPT), employing magnetic graphene oxide (MGO) as the adsorbent. The (GO) was produced through an oxidation and exfoliation method, magnetization technique by co-precipitation method. nanomaterials were characterized FTIR, XRD, SEM, Raman, VSM analysis. optimal condition reached GO·Fe3O4 at pH 3.0 (50 mg adsorbent 50 L?1 CPT), presenting values removal percentage maximum adsorption capacity 99.43% 100.41 g?1, respectively. CPT dependent on dosage, initial concentration adsorbate, pH, ionic strength. Sips Elovich models showed best adjustment for experimental data, suggesting that occurs in heterogeneous surface. Thermodynamic parameters reveal favorable, exothermic, involving chemisorption process. carbon nanomaterial exhibited after five adsorption/desorption cycles. Finally, excellent performance removal, allowing future application waste management.

متن کاملP23: The Effects of Captopril, as Angiotensin Converting Enzyme Inhibitor, on LPS-Induced Systemic Inflammation
It has been shown that the renin-angiotensin system (RAS) plays key roles in the inflammation process. Imbalance in the oxidant-antioxidant system is one of the major causes of inflammation. In the present study, the effects of captopril on total and differential WBC, oxidative stress in systemic inflammation produced by lipopolysaccharide (LPS) were investigated. The rats were divided to: cont...

The direct effects of a renin inhibitor, N-acetyl-pepstatin and five angiotensin converting enzyme inhibitors, captopril and the active diacid forms of enalapril, ramipril, cilazapril, and CS-622, on the vascular renin-angiotensin system were examined in isolated perfused rat mesenteric arteries. Vascular renin activity and angiotensin II (Ang II) released into the perfusate were determined. In...
