In the present study, biomass fiber (Luffa cylindrica) has been successfully used as biosorbent for the removal of a cationic dye namely, methylene blue, from aqueous solution using a batch process. The characterization of the biosorbent was carried out by the infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The chemical composition has been established by the energy dispersive X-Ray spectroscopy (EDS). The effects of various parameters such as the contact time (0-160 min), solution pH (2-10), biosorbent dose (0.5-8 g L -1 ), particle size, initial MB concentration (20-300 mg L -1 ) and temperature (20-60°C) were optimized. The biosorption isotherms were investigated by the Langmuir, Freundlich, Dubinin-Radushkevich and Tempkin models. The data were well fitted with the Langmuir model, with a maximum biosorption capacity of 49.46 mg g -1 at 20°C. The kinetics data were analyzed by the pseudo-first-order and pseudo-second-order models. The mass transfer model in terms of interlayer diffusion was applied to examine the mechanisms of the rate-controlling step (R 2 = 0.9992-0.9999). The thermodynamic parameters: free energy (DG°= -5.428 to -3.364 kJ mol -1 ), enthalpy (DH°= -20.547 kJ mol -1 ) and entropy (DS°= -0.052 kJ mol -1 K -1 ) were determined over the temperatures range (20-60°C). The results indicate that Luffa cylindrica could be an interesting biomass of alternative material with respect to more costly adsorbents used nowadays for dye removal.

ÖzBu çalışmada yüzeyi nano manyetit ile kaplanmış Eucalyptus camaldulensis kabukları (NEK), bir tekstil boyar maddesi olan Reaktif Black 39"un (RB39) distile su ve sentetik atıksudan gideriminde düşük maliyetli bir adsorbent olarak kullanılmıştır. Adsorpsiyon üzerine temas zamanı, pH, sıcaklık NEK dozu ve başlangıç boyar madde konsantrasyonu gibi çeşitli parametrelerin etkisi araştırılmıştır. Çalışmalar NEK"in adsorpsiyon kapasitesinin başlangıç boyar madde konsantrasyonunun, pH"ın ve sıcaklığın artmasıyla arttığını, NEK dozunun artmasıyla azaldığını göstermiştir. 300 mg/L RB39"un 150 mL distile sudan yaklaşık %94 verimle giderilmesi için 0,2 g NEK yeterli olduğu tespit edilmiştir. Diğer taraftan 300 mg/L RB39"un sentetik atıksudan yaklaşık %92 verimle giderilmesi için 0,4 g NEK"in yeterli olduğu bulunmuştur. Freundlich izotermi (R 2 =0,993) adsorpsiyon sürecini Langmuir izotermine göre daha etkili bir şekilde açıklamıştır. Langmuir izotermi NEK"in maksimum adsorpsiyon kapasitesini 432,12 mg/g olarak tahmin etmiştir. Anahtar Kelimeler: Adsorpsiyon, Eucalyptus camaldulensis, Manyetit Removal of Reactive Black 39 Dye from Distilled Water and Synthetic Wastewater by a Nano Adsorbent AbstractIn the present study, nano magnetite coated Eucalyptus camaldulensis barks (NEC) was used as a lowcost adsorbent for the removal of a textile dye Reactive Black 39 (RB39) from distilled water and synthetic wastewater. The effects of the various parameters, contact time, pH, temperature, NEC dosage and initial dye concentration on the adsorption were investigated. It was found that the adsorption capacity of NEC increases by increasing the RB39 concentration, pH and temperature and by decreasing the dosage of NEC. 0.2 g NEC was found to be sufficient for the removal of 300 mg/L RB39 from 150 mL distilled water with ∼94 % removal efficiency. On the other hand 0.4 g NEC was found sufficient for the removal of RB39 from synthetic wastewater with ∼92 % removal efficiency. The Freundlich isotherm model described the adsorption process more effectively (R 2 = 0.993) than the Langmuir isotherm model. The Langmuir isotherm predicted a 432.12 mg/g maximum adsorption capacity of NEC.

Bamboo is used as a raw material for producing chopsticks, artifacts, utensils, plywood, fiberboard, and decorated multi-layered panels. The manufacturing process generates a large amount of bamboo residual waste. In this study, bamboo-derived fuels were prepared from the residual waste of Dendrocalamus latiflorus, Phyllostachys makinoi, and Phyllostachys pubescens. The combustion behaviors of bamboo-derived fuels were also investigated. The characteristics of derived fuels made from bamboo waste with engine oil waste showed that the ash content was less than 5% and that the calorific value reached 5,000 kcal/kg, which was higher than derived fuels standards. Additionally, the derived fuel of bamboo waste had a high combustion efficiency and low nitrogen, sulfur, and chlorine emission levels, which were lower than the derived fuels standards. Thus, bamboo-derived fuel prepared from Dendrocalamus latiflorus, Phyllostachys makinoi, and Phyllostachys pubescens waste mixed with engine oil waste is a suitable fuel alternative.
