“…From Figure a, the surface of Raw-PFL was rough and not uniform while NaOH-PFL (Figure b) demonstrated a more well-developed heterogenous porous structure due to NaOH modification. The porosity development can be related to the dehydration effect, where lignocellulosic structures were broken down under high temperature followed by volatilization. , The rupture of some pores is attributed to the formation of larger and more heterogeneous pores after NaOH modification. , The reaction then reduces sodium hydroxide to metallic sodium (Na), sodium carbonate (Na 2 CO 3 ), and hydrogen gas (H 2 ) by following the reaction 6NaOH + 2C → 2Na + 3H 2 + 2Na 2 CO 3 . , As indicated in the EDX spectra (Figure c,d) and summarized in Table , the major elements presented in both adsorbents are carbon (C) and oxygen (O) with traces of calcium (Ca), phosphorus (P), and magnesium (Mg). After the modification by NaOH, the carbon composition was overserved to be increased along with the decrease in oxygen atom.…”

“…The scanned micrographs of CWL before adsorption in Figure 3a shows rough surface morphology with irregular defects, cracks and cavities. However, the crack widens after adsorption and the pores are filled with deposits of MG molecules adsorbed The effect of pH on adsorption can be described based on the point of zero charges (PZC), which is the point at which the net charge of the adsorbent is zero (Asim et al, 2019). the PZC of the adsorbent is 8.80 which shows a perfect charge balance in the basic region.…”

This study aimed to investigate the potential of carbonized water lily leaves (CWL) as cheap adsorbent for the adsorption of Malachite Green (MG) dye. The CWL characteristics were studied using Fourier Transform Infra-Red (FTIR) spectroscopy, Scanning Electron microscopy (SEM) and point of zero charge (PZC) to establish surface functional groups present, morphology and net neutral charge of the adsorbent. The effects of contact time (15-150min), dosage (20-200mg), initial concentration (20-140ppm), and pH (3-13) on the adsorption process were investigated for the removal of MG by batch adsorption method. The result shows that all the parameters have effect on adsorption process. Compared to the Langmuir, Freundlich, Temkin, and D-R models, the isotherm models were investigated and confirmed to fit well onto the D-R model. Pseudo-second order model best fitted the kinetic data for the different operating temperature (300C, 400C, 500C) of the analysis. Thermodynamics studies clearly indicates that the sorption was spontaneous, endothermic, and increased in the randomness of the systems at adsorbent-liquid interfaces as a result of negative Gibb’s free energy (∆G), positive enthalpy (∆H) and Entropy (∆S). Therefore, this study confirmed that carbonized water lily leaves adsorbent could be used as an alternative adsorbent for the adsorption of toxic dyes such as Malachite green dye.

The present work represent potential bio-sorbent (banana and pomegranate peel) in nano size range, with a view to for adsorption of lead(II) ions from aqueous solution. Dose, adsorbate concentration, pH, time, and temperature factors were investigated. The most favorable stipulations for Pb (II) adsorption are 50 mg /L as initial concentration, 0.2 g as pomegranate and banana peels mass and pH 5.5 and 5.23for banana and Pomegranate peel. Removal data obey the Langmuir model with qmax of 25.64 mg/g for banana and 41.66 mg/g for Pomegranate peel. The kinetics of removal process was fitted well by a second -order equation. It was observed that that the Pb (II) ion adsorption process on the both bio-sorbents is spontaneous process, endothermic for banana while exothermic for pomegranate peel. A distinct improvement in the adsorbent surface was noted after adsorption process which demonstrated via scanning electron microscope.
