DATA FROM: PRODUCTION OF BIOADSORBENT FROM PHOSPHORIC ACID PRETREATED PALM KERNEL SHELL AND COCONUT SHELL BY TWO-STAGE CONTINUOUS PHYSICAL ACTIVATION VIA N2 AND AIR
DESCRIPTION : In the present study, agricultural biomass; palm kernel shell (PKS) and coconut shell (CS) were used to produce high porosity bioadsorbent using two-stage continuous physical activation method with different gas carrier (air and N2) in each stage. The activation temperature was set constant at 600°C, 700°C, 800°C or 900°C for both activation stages with the heating rate of 3°C min-1. Two parameters including the gas carrier and activation temperature were determined as the significant factors on the adsorption properties of bioadsorbent. BET, SEM, FTIR, TGA, CHNS/O and ash content were used to elucidate the developed bioadsorbent prepared from PKS and CS and its capacity towards the adsorption of methylene blue and iodine. The novel process of two-stage continuous physical activation method was capable to emerge mesopores and micropores that were previously covered/clogged in nature, and simultaneously creating new pores. The synthesized bioadsorbents showed that the surface area (PKS: 456.47 m2 g-1; CS: 479.17 m2 g-1), pore size (PKS: 0.63 nm: CS: 0.62 nm) and pore volume (PKS: 0.13 cm3 g-1, CS: 0.15 cm3 g-1) were significantly higher than that of non-treated bioadsorbent. The surface morphology of the raw materials and synthesized bioadsorbent were accessed by SEM. Furthermore, the novel process meets the recent industrial adsorbent requirements such as low activation temperature, high fixed carbon content, high yield, high adsorption properties and high surface area which are the key factors for large scale production of bioadsorbent and its usage.

DFT ANALYSIS OF 3-(4-METHOXYPHENYL)-1-PHENYLPROP-2-EN-1-ONE (MNYAD_1539) IN GAS PHASE
DESCRIPTION : The molecules were constructed using Avogadro. The calculations were performed with the program Gaussian 09 (g09). The method used was density functional theory (DFT) utilizing B3LYP function and 6-31G*/6-31G* basis set. A second set of calculations were performed with DFT and B3LYP functional this time using 6-31G*/cc-PVTZ basis set. The g09 outputs were processed with Avogadro and the calculated transmission IR spectra were generated.

EFFICIENT REMOVAL OF PHARMACEUTICALS FROM WATER USING GRAPHENE NANOPLATELETS AS ADSORBENT
DESCRIPTION : Recently, pharmaceutical pollutants in water emerge as global concern as they give threat to human health and environment. In this study, graphene nanoplatelets (GNPs) were used to efficiently remove antibiotics sulfamethoxazole (SMX) and analgesic acetaminophen (ACM) as pharmaceutical pollutants from water by adsorption process. GNPs; C750, C300, M15, and M5 were characterized by high-resolution transmission electron microscopy, Raman spectroscopy, X-Ray diffraction and Brunauer-Emmett-Teller. The effects of several parameters; viz., solution pH, adsorbent amount, initial concentration and contact time were studied. The parameters were optimized by batch adsorption process and the maximum removal efficiency for both pharmaceuticals were 99%. The adsorption kinetics and isotherms model were employed, and the experimental data were best analysed with pseudo-second kinetic and Langmuir isotherm with maximum adsorption capacity (Qm) of 210.08 mg g-1 for sulfamethoxazole and 56.21 mg g-1 for acetaminophen. Regeneration study were applied using different eluents; 5% ethanol-deionized water 0.005 M NaOH and HCl. GNP C300 were able to remove most of both pollutants from environmental water samples. Molecular docking was used to simulate the adsorption mechanism of GNP C300 towards sulfamethoxazole and acetaminophen with free binding energy of -7.54 kcal mol-1 and -5.29 kcal mol-1 respectively which revealed adsorption occurred spontaneously.
