“…Adsorption isotherms were obtained by measuring the amount of N 2 adsorbed to the surface of both biosorbents at 77.26 K. Desorption isotherms were derived by removing the N 2 adsorbed through a gradual pressure reduction. The methods used to characterize the DP and ATDP are reported elsewhere [25,40,41].…”

Durian peel (DP) is an agricultural waste that is widely used in dyes and for organic and inorganic pollutant adsorption. In this study, durian peel was acid-treated to enhance its mycotoxin adsorption efficacy. The acid-treated durian peel (ATDP) was assessed for simultaneous adsorption of aflatoxin B1 (AFB1), ochratoxin A (OTA), zearalenone (ZEA), deoxynivalenol (DON), and fumonisin B1 (FB1). The structure of the ATDP was also characterized by SEM–EDS, FT–IR, a zetasizer, and a surface-area analyzer. The results indicated that ATDP exhibited the highest mycotoxin adsorption towards AFB1 (98.4%), ZEA (98.4%), and OTA (97.3%), followed by FB1 (86.1%) and DON (2.0%). The pH significantly affected OTA and FB1 adsorption, whereas AFB1 and ZEA adsorption was not affected. Toxin adsorption by ATDP was dose-dependent and increased exponentially as the ATDP dosage increased. The maximum adsorption capacity (Qmax), determined at pH 3 and pH 7, was 40.7 and 41.6 mmol kg−1 for AFB1, 15.4 and 17.3 mmol kg−1 for ZEA, 46.6 and 0.6 mmol kg−1 for OTA, and 28.9 and 0.1 mmol kg−1 for FB1, respectively. Interestingly, ATDP reduced the bioaccessibility of these mycotoxins after gastrointestinal digestion using an in vitro, validated, static model. The ATDP showed a more porous structure, with a larger surface area and a surface charge modification. These structural changes following acid treatment may explain the higher efficacy of ATDP in adsorbing mycotoxins. Hence, ATDP can be considered as a promising waste material for mycotoxin biosorption.

“…The surface morphology of the raw durian husk before activation, DHAC before Pb(II) adsorption, DHAC after Pb(II) adsorption as well as after Pb(II) desorption was determined by scanning electron microscopy (SEM Model S‐3400N, Hitachi High‐Technologies Co., Japan) addition, surface area and pore size of pristine biosorbent, and DHAC were examined using the Brunauer, Emmett and Teller (BET) single point method. It was analyzed with surface characterization analyzer (Model 170, Micromeritics 3 flex 1.02, USA) degas temperature of 200 °C was adopted , and the samples were out‐gassed by passing dry nitrogen for a specific duration over the samples in order to clean any unwanted matter, e.g. moisture content or dust particles that would interfere, especially by blocking the pores available on the surface of the biosorbent .…”

Background Biosorption of lead Pb(II) by durian husk activated carbon (DHAC) was investigated. The main aim of this work is to explore the effect of operating variables such as pH, biosorbent dose, temperature, initial metal ion concentration and contact time on the removal of Pb(II) from synthesized aqueous medium using a response surface methodology (RSM) technique. The experimentation was performed in two sets, namely set 1 and set 2. Results For experimental set 1, pH was set to 7.0. The optimum conditions for the remaining parameters were determined to be 0.39 g DHAC dose, 60 min contact time and 100 mg L−1 of initial metal ion concentration, which yielded maximum biosorption capacity of 14.6 mg g−1. For experimental set 2, 41.27 °C, 8.95 and 99.96 mg L−1 were the optimum conditions determined for temperature, pH and initial Pb(II) concentration, respectively; which revealed a maximum adsorption capacity of 9.67 mg g−1. Characterization of the adsorbent revealed active functional groups such as hydroxyl, carboxylic, alcohol and hemicellulose. The equilibrium adsorption data obeyed the Langmuir isotherm and pseudo‐second‐order kinetic models with maximum Langmuir uptake of 36.1 mg g−1. Conclusions The biosorbent was capable of reuse, so that the abundant durian husk could be utilized effectively for the removal of Pb(II) from polluted water. © 2018 Society of Chemical Industry

“…The adsorption testing that was carried out refers to the study of Ibadurrahman (Ismail et al, 2010) who used a beam box measuring 20 cm × 10 cm × 18 cm made of acrylic glass as a representation of the state of space for cigarette smoke adsorption media. The test variables used were activated carbon, TiO2, and modified TiO2 activated carbon against pure CO gas pollutants, cigarette smoke, 10% metaldehyde, 37% methanol solution, and acetaldehyde.…”

Activated carbon is one solution to overcome the problem of cigarette smoke which is very dangerous for health where durian shell waste is chosen as the base material. Durian shell waste was chosen because it contains high cellulose, lignin, and starch. Its production also reaches 746,805 thousand tons per year. Durian shell waste that had been activated by chemical activation with K2CO3 versus activated carbon is 1:1, 3:2, and 2:1, and by physical activation with N2 was then modified with MgO with variations in concentrations of 0.5%, 1%, and 2% at 450 o C for 30 minutes. Activated carbon and modified activated carbon were then characterized by the Iod Number test, BET test, SEM test, and EDX test. The best non-modified activated carbon was the carbon which was chemical and physically activated at ratio 3:2 with results of 41.56% in yield, 399.44 mg/g in iodine numbers, and 694.13 m 2 /g in surface area. While the best modified activated carbon was at MgO concentration of 2% with a yield of 97%, an iodine number of 625.70 mg/g, and a surface area of 1,029.90 m 2 /g. The CO gas adsorption application, which is the component with the largest contribution in cigarette smoke, and cigarette smoke itself were tested using modified activated carbon. The results showed that 2% modified activated carbon was the best type of activated carbon to degrade CO in 3.89%/gram per minute with an adsorption ability of 0.215%. This activated carbon was also able to purify the air from the cigarette in 8.04%/gr activated carbon per minute with an adsorption ability of 0.87%.
