Özet
Worldwide water sources continue to be polluted daily by various additives, of which dyestuffs are a significant contributing factor. In the present study, Rumex Crispus L. (RCL) was used as a biomass bio-adsorbent, and the adsorption of methylene blue on RCL was investigated. RCL was characterized using Brauner–Emmett–Teller, Fourier transform infrared, X-ray diffraction, and scanning electron microscopy (SEM) analyses. The effects of the RCL amount (0.5–6 g/L), initial pH (3–10), concentration (40–200 mg/L), contact time (0–60 min), and temperature (293–313 K) on adsorption activities were investigated, and the point of zero charge value of the adsorbent was determined. Thermodynamic studies have shown that adsorption occurs spontaneously and exothermically (ΔG0 = − 2.19 to − 0.72 kJ/mol, ΔH0 = − 23.8 kJ/mol, ∆S0 = − 0.074 kJ/mol). Pseudo-first-order, pseudo-second-order, intraparticle diffusion …
