Adsorption of reactive dye Remazol Brilliant Blue R from aqueous solutions by rambutan peel

Abstract

Adsorption of Remazol Brilliant Blue R (RBBR) by rambutan peel (RP) was examined. The adsorption experiments were carried out under different conditions of initial concentration (25-500 mg/L), solution pH 2-12 and RP dose (0.05-1.2 g). The influence of these parameters on the adsorption capacity was studied using the batch process. RBBR adsorption uptake was found to increase with increase in initial concentration and contact time. The RBBR adsorption was favourable at pH<4. Langmuir, Freundlich and Temkin isotherm models were used to illustrate the experimental isotherms and isotherms constant. The equilibrium data were best represented by Langmuir isotherm model, showing maximum monolayer adsorption capacity of 112.69 mg/g. The rates of adsorption were found to obey the rules of pseudo-second order model with good correlation. The results suggested that RP has high potential to be used as effective adsorbent for RBBR removal.

Agricultural peels for dye adsorption: A review of recent literature

“…The adsorption of RBB and MB blue onto raw rambutan peel and treated with NaOH was examined [70,71]. In the case of RBB, the optimum pH value was lower than 4, but for MB was higher than 4.…”

Pengaruh pH dan Waktu Kontak Pada Adsorpsi Remazol Brilliant Blue R Menggunakan Adsorben Ampas Singkong

“…Xie et al, (2014) juga menggunakan ampas singkong untuk adsorpsi Cu (II) [7]. Sementara pada penelitian yang dilakukan oleh Alrozi et al, (2012), selulosa yang terdapat pada kulit rambutan juga dimanfaatkan sebagai adsorben Remazol Brilliant Blue R [9]. Pada penelitian lain yang juga memanfaatkan limbah lignoselulosa dilakukan oleh [10], dimana penelitian ini menggunakan kulit jeruk sebagai adsorben untuk zat warna Remazol Brilliant Blue R [10].…”
