“…Charcoal was ball-milled (PM 100-RETSCH, Shimadzu, Japan) and made into nanoparticles. The activation process was carried out by immersing the material in liquid smoke for 24 h. The carbon nanoparticles were then collected by filtration, washed several times with aquadest, and then dried to constant weight in an oven at 105 °C to remove remaining water [23]. The schematic diagram of the adsorbent preparation can be seen in Fig.…”

“…One such adsorbent is charcoal derived from the pyrolysis residue of oil palm shell (in liquid smoke production), which has not hitherto been widely utilized [22]. The current research has aimed to investigate the efficiency and kinetics of Cu 2+ adsorption by using nanocarbon derived from palm oil pyrolysis residue activated by liquid smoke; that is to say, exposed to compounds derived from biomass pyrolysis containing carboxylic acid, phenol, ketone, and aldehyde groups [23]. The use of residual charcoal and liquid smoke as its activating agent is expected to produce an inexpensive and effective adsorbent for Cu 2+ adsorption.…”

Copper (Cu 2+ ) ions has been recognized as hazardous heavy metal and having negative effects on human health, animal, plants, and environment. Therefore, the removal of Cu 2+ from contaminated water to an acceptable level is necessary. In this research, activated carbon prepared from palm kernel shell waste products has been used for the removal of Cu 2+ ions from aqueous solutions. The oil palm shells were pyrolyzed at 380 °C, producing charcoal and liquid smoke. The carbon material was modified to nano size and activated by liquid smoke to generate activated carbon with a well developed porous structure and distribution porosity. The activated carbon was then characterized by Fourier-transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). All experiments were conducted in a batch process with initial metal concentrations in the range 30-150 ppm, contact times in the range 30-150 min and at room temperature. The best conditions for high removal efficiency of Cu 2+ was investigated. The adsorption isotherm of the Langmuir and Freundlich models were used to analyze the data obtained. The kinetic of first and second-order models were also studied. The highest removal efficiency of 97.5% was obtained at a contact time of 60 min, an initial Cu 2+ concentration of 30 ppm, and an agitation speed of 200 rpm. The Freundlich isotherm model was well fitted (R 2 =0.937) and indicated pseudo-first-order chemisorption. Based on the results, the activated carbon with liquid smoke activation would be an alternative adsorbent in removing Cu 2+ from industrial wastewater.

This study aims to examine the possibility of utilizing Cu(II) modified liquid smoke as an antifungal agent against Schizophyllum commune Fr. in a laboratory test. The liquid smoke was obtained through the pyrolysis of oil palm kernel shells at 300°C, 340°C, and 380°C. The analysis of liquid smoke as an antifungal agent was performed using potato dextrose agar (PDA) media and nystatin as positive controls. The white-rot fungi of Schizophyllum commune Fr. were isolated from fungally infected wood and regenerated for 5x24 hours. Observation of the inhibiting zone was done in 24 hours. The results showed that the presence of Cu(II) can increase the inhibiting zone of white rot fungus. The Cu(II)-modified liquid smoke was able to significantly inhibit the growth of white-rot fungi even in low liquid smoke concentrations. The highest inhibiting zone of Schizophyllum commune Fr. was obtained with 3% Cu(II)-modified liquid smoke (obtained from a pyrolysis temperature of 380°C).

“…Nonetheless, the sizeable quantities of residual charcoal produced remain largely unused [26,27]. Some of this residual charcoal can be used to make briquettes [28] but its use as an adsorbent is limited to treating copper contamination [29]. This research aimed to determine the effectiveness of NaOH-activated palm shell charcoal by assessing its adsorption capacity, adsorption isotherm equilibria, (Langmuir and Freundlich), and adsorption kinetics toward cadmium.…”

This research aimed to convert the charcoal produced from palm kernel shell pyrolysis into activated carbon nanoparticles for use in the adsorption of cadmium, which is one of the most toxic (e.g., carcinogenic) heavy metals. In particular, the adsorption capacity, adsorption isotherm, and adsorption kinetics of cadmium onto the produced charcoal were determined. Pyrolysis of palm kernel shells at 380°C resulted in liquid smoke, tar, and charcoal. The charcoal was ground with a ball mill until it reached nanoparticle size. Subsequently, it was chemically activated by soaking it in a 0.1 N NaOH solution for 24 h. The pre-and post-activation charcoal was characterized using a scanning electron microscope (SEM). The carbon activated nanoparticles were then used in cadmium adsorption experiments at various contact times (30, 60, 90, 120, 150, and 180 min), several initial cadmium concentrations (30, 60, 90, 120, and 150 ppm), and two stirring speeds (100 and 150 rpm). The results showed that maximum adsorption capacity was reached at 22 mg/g with more than 97% adsorption efficiency. Two adsorption models, i.e., Langmuir and Freundlich, were used to interpret the equilibrium data. At the 100-rpm stirring speed, the Langmuir isotherm indicated a maximum adsorption capacity (qm) for cadmium of 22.37 g/mg (Kl = 0.131 mg/g, with a constant correlation of R 2 = 0.915). The Freundlich isotherm gave values of n = 1.503, Kf = 2.877 mg/g, and R 2 = 0.969. Therefore, these two models are considered suitable for describing the equilibrium cadmium adsorption isotherm in the presence of NaOH-activated palm kernel shell charcoal.
