Peanut shell-based activated carbon was prepared by 60% zinc chloride activation. The activation temperature was 923K and activation time was 90min. The activated carbon was applied on the removal of acid light yellow from wastewater. The effects of the amount of adsorbent, the initial dye concentration and pH value of solution were investigated. The results showed that the optimum conditions for dye removal: activated carbon dosage of 2.5g/L, initial dye concentration of 50mg/L, pH value of 3. The color removal efficiency attained above 95%. It is concluded that activated carbon developed from peanut shell could be effective and practical for utilizing in dye wastewater treatment.

Fast Extraction

Herein, a facile and low-cost method for the preparation of activated carbon from peanut shell was developed for the first time for the fast extraction and determination of Bisphenol A in human urine. Bisphenol A was separated by EC-C18 column (250 mm×4.6 mm, 4 μm) and was detected by VWD, with retention time for qualitative analysis and peak area for quantitation. The parameters, pH values of the urine, adsorbent dose, adsorption time and so on, were optimized to achieve the excellent extraction performance. The detection limit of Bisphenol A in human urine was 1.0 ng · mL−1 (S/N = 3), and the standard curve was linear in the range of 5.0 ng · mL−1˜200.0 ng · mL−1 (r = 0.9993). The average recovery of Bisphenol A was 78.5˜96.2% at three spiked levels in the range of 5.00 ng · mL−1˜200.00 ng·mL−1. The method was proved simple, practical and highly sensitive, which could satisfy the request for the determination of Bisphenol A in human urine.

Initial Adsorption Rate

A pseudo-second-order rate equation describing the kinetic adsorption of phenol onto peanut shell acid-activated carbon at different initial concentrations, carbon dosages and particle sizes has been developed. The adsorption kinetics were followed on the basis of the amount of phenol adsorbed at various time intervals at 22°C. The rate constant and the equilibrium adsorption capacity were calculated. From these parameters, empirical correlations for predicting the equilibrium adsorption capacity as a function of the C0/D ratio, and for estimating the rate constant as a function of the relation D/(C0dp)0.5, were derived. This allowed a general rate expression for design purposes to be obtained which was valid for C0/D ≤ 1.5. The operation line for each case studied was constructed and the equilibrium adsorption capacity obtained. A comparison was undertaken with the experimental adsorption isotherm as previously determined. The effect of the initial phenol concentration, the carbon dose and the particle size on the initial adsorption rate was also analyzed.

Symmetric Supercapacitor

Biomass-waste activated carbon/molybdenum oxide/molybdenum carbide ternary composites are prepared using a facile in-situ pyrolysis process in argon ambient with varying mass ratios of ammonium molybdate tetrahydrate to porous peanut shell activated carbon (PAC). The formation of MoO2 and Mo2C nanostructures embedded in the porous carbon framework is confirmed by extensive structural characterization and elemental mapping analysis. The best composite when used as electrodes in a symmetric supercapacitor (PAC/MoO2/Mo2C-1//PAC/MoO2/Mo2C-1) exhibited a good cell capacitance of 115 F g−1 with an associated high specific energy of 51.8 W h kg−1, as well as a specific power of 0.9 kW kg−1 at a cell voltage of 1.8 V at 1 A g−1. Increasing the specific current to 20 A g−1 still showcased a device capable of delivering up to 30 W h kg−1 specific energy and 18 kW kg−1 of specific power. Additionally, with a great cycling stability, a 99.8% coulombic efficiency and capacitance retention of ~83% were recorded for over 25,000 galvanostatic charge-discharge cycles at 10 A g−1. The voltage holding test after a 160 h floating time resulted in increase of the specific capacitance from 74.7 to 90 F g−1 at 10 A g−1 for this storage device. The remarkable electrochemical performance is based on the synergistic effect of metal oxide/metal carbide (MoO2/Mo2C) with the interconnected porous carbon. The PAC/MoO2/Mo2C ternary composites highlight promising Mo-based electrode materials suitable for high-performance energy storage. Explicitly, this work also demonstrates a simple and sustainable approach to enhance the electrochemical performance of porous carbon materials.
