“…This indicated that initial active binding sites on biosorbent are easily occupied by copper (II) ions and subsequent saturation phase was due to saturation of active binding sites thus, the observed equilibrium status. A similar trend of observation for tree leaves biosorbents was reported by Sangi et al [8] and Kilic et al [9] whereby reaction proceeded with a high rate initially and followed by a stage of no significant changes with further increase in contact time. Based on this result, further experiments were conducted under equilibrium status with 10 minutes of contact time.…”

“…At the equilibrium stage, there is no changes of biosorption due to the saturation of available binding sites. Sangi et al [9] and Kilic et al [10] reported similar observation for Cu (II) biosorption when used tree leaves biosorbents. Similarly, studies for Ni (II) biosorption using cone and sawdust biosorbents also showed consistent results [11,12].…”

Biosorption behavior of Pleurotus mushroom spent-substrate was studied using two divalence cations: Ni(II) and Cu(II). Biosorption of both cations showed similar behavior on the effect of pH, initial concentration, temperature and contact time. Optimum biosorption was found to be between pH of 5-6, while lower initial concentration and temperature (as low as 10 mg.L -1 and 5 o C), increased the biosorption efficiency. Rapid biosorption was observed to occur within 4-5 minutes of contact time. Therefore, metal removal using PMSS as the biosorbent needs to address the four fundamental parameters. ABSTRAKKelakuan biopenjerapan bagi substrat terpakai cendawan Pleurotus dikaji dengan menggunakan dua kation dua valensi iaitu Ni(II) dan Cu(II). Faktor pH, kepekatan awal larutan, suhu dan masa interaksi memberikan kesan yang sama terhadap kedua kation yang dikaji. pH 5-6 merupakan paras pengoptimuman biopenjerapan. Sementara itu, kepekatan awal larutan dan suhu yang rendah (serendah 10 mg.L -1 dan 5 o C) telah meningkatkan kecekapan biopenjerapan. Kadar biopenjerapan maksima berlaku dalam tempoh masa bersentuhan selama 4-5 minit. Oleh itu, faktor pemboleh-ubah operasi penyingkiran logam dengan menggunakan PMSS sebagai bahan biopenjerap perlu mengambilkira empat kelakuan asas.(Keywords: biosorption behavior, Pleurotus sp., metal, mushroom spent-substrate)

“…The adsorption capacity of clinoptilolite is significantly affected by physical and chemical pretreatment and loading or regeneration of clinoptilolite. The pretreatment of natural zeolites by acids, bases, surfactants, etc ., is an important method to improve their ion-exchange capacity [8,13,14,15,16]. Practically, the result of any pretreatment operation is the increase of the content in a single cation, what is called homoionic form.…”

The adsorption isotherm, the adsorption kinetics, and the thermodynamic parameters of ammonium removal from aqueous solution by using clinoptilolite in aqueous solution was investigated in this study. Experimental data obtained from batch equilibrium tests have been analyzed by four two-parameter (Freundlich, Langmuir, Tempkin and Dubinin-Radushkevich (D-R)) and four three-parameter (Redlich-Peterson (R-P), Sips, Toth and Khan) isotherm models. D-R and R-P isotherms were the models that best fitted to experimental data over the other two- and three-parameter models applied. The adsorption energy (E) from the D-R isotherm was found to be approximately 7 kJ/mol for the ammonium-clinoptilolite system, thereby indicating that ammonium is adsorbed on clinoptilolite by physisorption. Kinetic parameters were determined by analyzing the nth-order kinetic model, the modified second-order model and the double exponential model, and each model resulted in a coefficient of determination (R2) of above 0.989 with an average relative error lower than 5%. A Double Exponential Model (DEM) showed that the adsorption process develops in two stages as rapid and slow phase. Changes in standard free energy (∆G°), enthalpy (∆H°) and entropy (∆S°) of ammonium-clinoptilolite system were estimated by using the thermodynamic equilibrium coefficients.
