Title: Synthesis and Characterization of Low-Cost Wood based Biosorbent Authors: Yennam, Rajesh; Lakshmana Rao, Jeeru Abstract: The purpose of this study is to prepare and characterize natural wood-based biosorbents from India’s Northwest region. Biosorbents were prepared using banana pith, pineapple and bamboo stems. The preparation procedure for the biosorbents involved sequential processing steps such as washing, drying, grinding and chemical treatment using phosphoric acid and NaOH. Finally, the prepared biosorbents were sieved to different mesh sizes ranging from 80 to 230 meshes. Biosorbent characterization were carried out using BET, SEM, FTIR and TGA. Prior to chemical treatment, the biosorbents were evaluated with BET method and the surface areas obtained are 3.574, 5.678 and 9.072 m2/g for banana pith, bamboo and pineapple stem based biosorbents respectively. However, chemical treatment method enhances the BET surface area to 100.16 and 116.01 m2/g for banana pith and bamboo stem based biosorbents respectively. The average particle sizes of the biosorbents were determined as 30, 63, and 78 (mm) for biosorbents prepared from pineapple stem, banana pith, and bamboo stem respectively. TGA provided the measurement of the mass variation of the biosorbent with variation in temperature and time. For a heating rate of 10 C/min, TGA results indicated that the maximum temperature to withstand were 65, 129, and 200 C for biosorbents prepared with pineapple stem, banana pith and bamboo stem respectively. The obtained characterization results for the biosorbents are indicative of their promising application towards the removal of heavy metals from wastewater streams.

Title: Equilibrium and Kinetic Studies of Ni (II) Adsorption using Pineapple and Bamboo Stem Based Adsorbents Abstract: This work addresses the preparation and characterization of inexpensive adsorbents for the removal of Ni (II) from aqueous solutions. Activated carbon based adsorbents have been prepared from plant based biomass resources, namely Pineapple stem (Ananas Comosus) and Bamboo Stem (Bambuseae). Adopting phosphoric acid and heat treatment techniques, it has been observed that the bamboo stem activated charcoal (BSAC) and pineapple stem (PS) adsorbents had a BET surface area of 116 and 11.47m2/g, respectively. FTIR analysis indicated that various surface functional groups (such as C≡N stretching, stretching vibration of C=O, –CH3 wagging and C–O stretching vibration) contribute towards Ni (II) adsorption. Batch mode adsorption experiments were conducted for these adsorbents in the range of 50–300mg/L Ni (II) solution concentration, 2–10 pH, 15–300 min. contact time, and 0.02–0.1 g/50mL dosage. The BSAC adsorbent has been characterized with a metal uptake and %removal of 121.72 mg/g and 92.47, respectively, which corresponds to 45% higher metal uptake than corresponding bamboo based adsorbents presented in the literature. Further experimentation with BSAC enabled to achieve activated charcoal with surface area values similar to that of the commercial activated carbon adsorbent. The bamboo adsorbent has also been evaluated to perform similar to the commercial activated carbon for the removal and recovery of Pd (II) from synthetic electroless plating solutions. Also, a conceptual cost analysis indicated and affirmed towards the potential of the BSAC adsorbents for waste water treatment applications.
