Introduction to Green Adsorption

What is/are Green Adsorption?

Green Adsorption - 5 g), shaking speed (150–250 rpm), pH (4–7), temperature (20°C–50°C), and particle size (137–892 μm) on methyl green adsorption on the almond shell were examined. ^[1] It was found that the optimum parameters of pH, initial concentration and contact time for malachite green adsorption on nanoporous silica were 6. ^[2] 3 m2/g and 1123 m2/g respectively; and maximum malachite green adsorption capacities were 58 mg/g and 98 mg/g respectively. ^[3] Kinetic calculations confirmed that malachite green adsorption was described more accurately by pseudo-second order model compared to the pseudo-first order model. ^[4] The adsorption kinetics study showed that malachite green adsorption onto both pristine and intercalate LDH followed the pseudo-2nd-order model. ^[5] The results showed that the optimum conditions for Malachite green adsorption occurred at pH 3, a concentration of 100 ppm 8,0662 mg/g. ^[6] The green adsorption–desorption of EDC from polypropylene membrane protected µ-SPE device was optimised at sorbent loading of 2 mg, extraction time of 30 min, sodium chloride of 15% (w/v), medium pH of 8, a sample volume of 10 mL, desorption solvent of isopropanol, desorption time of 3 min and desorption solvent volume of merely 150 µL. ^[7] 0-µm pixel image sensor, improved spectral characteristics owing to green adsorption by the organic film above the red/blue photodiode, were successfully demonstrated. ^[8] Thermodynamic parameters of $$\Delta {G}^{0}$$ΔG0 and $$\Delta {H}^{0}$$ΔH0 verified the spontaneous and endothermic nature of the brilliant green adsorption onto ZnO/PPy. ^[9] The maximum malachite green adsorption capacity was obtained 317. ^[10] Bromocresol green adsorption kinetics followed a pseudo-second-order kinetic model, indicating that adsorption was the rate-limiting step. ^[11] Crystal violet adsorption was exothermic with increase in ∆G values, whereas Brilliant green adsorption was endothermic in nature with decrease in ∆G in the temperature range 293–323 K. ^[12] Malachite green adsorption took place only on lower-energy sites. ^[13] The optimum malachite green adsorption occurred at pH 10 and the equilibrium reached after 180 min. ^[14]

Malachite Green Adsorption

Brilliant Green Adsorption

Thermodynamic parameters of $$\Delta {G}^{0}$$ΔG0 and $$\Delta {H}^{0}$$ΔH0 verified the spontaneous and endothermic nature of the brilliant green adsorption onto ZnO/PPy. ^[1] Crystal violet adsorption was exothermic with increase in ∆G values, whereas Brilliant green adsorption was endothermic in nature with decrease in ∆G in the temperature range 293–323 K. ^[2]

The adsorption kinetics study showed that malachite green adsorption onto both pristine and intercalate LDH followed the pseudo-2nd-order model. ^[1] Thermodynamic parameters of $$\Delta {G}^{0}$$ΔG0 and $$\Delta {H}^{0}$$ΔH0 verified the spontaneous and endothermic nature of the brilliant green adsorption onto ZnO/PPy. ^[2]
