TLDR
In this paper, karanj (Pongamia pinnata ) fruit hulls were used as a precursor to prepare low-cost activated carbon with a large surface area through KOH activation.Abstract:
In this study, karanj ( Pongamia pinnata ) fruit hulls were used as a precursor to prepare low-cost activated carbon with a large surface area through KOH activation. The prepared activated carbon (KFHAC) was characterized through pore structural analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy. KFHAC presents a BET surface area of 828.30 m 2 /g, a micropore volume of 0.36 cm 3 /g, and an average pore size of 19.92 A The adsorption performance of KFHAC was evaluated using methylene blue (MB) as the model adsorbate. Adsorption experiments indicated that the pseudo-second-order kinetic and Langmuir adsorption isotherm models can accurately describe the adsorption process. The maximum adsorption capacities ( q m ) of MB were 154.8, 203.4, and 239.4 mg/g at 30 °C, 40 °C, and 50 °C, respectively. This study indicates that karanj fruit hull is a promising precursor for the production of low-cost and efficient activated carbon with a large surface area.read more

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.
