“…6) because the principal bands of silicon compounds of pumice were identified at 460 and *800 cm -1 and a strong peak around 1,047 cm -1 , which can be associated with the Si-O bending strength vibrations and the Si-O stretching vibrations (Ersoy et al 2010). Also, a broadband located at 3,423 cm -1 was observed, which corresponds to O-H stretching vibration in hydroxyl functional groups, and the band at 2,922 cm -1 and its shoulder at 2,856 cm -1 could be attributed to mC-H and dC-H (m = stretching and d = bending) absorption bands that may be associated with methyl and methylene groups (Deng et al 2010;Tian et al 2011). The band at 1,630 cm -1 can be attributed to C=O vibrations of ketones, aldehydes or carboxylic acids.…”

In this study, the denim fiber scraps were reused as an alternative low-cost sorbent for the removal of heavy metals Pb 2? , Cd 2? , Zn 2? and arsenic from aqueous solutions. Results showed that this textile waste was an effective sorbent for the removal of these heavy metal ions and offered a better removal performance than those reported for other synthetic and natural sorbents such as activated carbons and zeolites. On the other hand, raw and metal-loaded denim wastes were also useful for the removal of arsenic (V) from aqueous solutions and their sorption capacities were higher than 1.5 mg/g. In particular, the presence of Pb 2? ions on the surface of denim wastes improved significantly its arsenic (V) sorption performance. In summary, the reuse of denim textile wastes in wastewater treatment can be considered as an eco-friendly application that could be useful for waste management and also for reducing the production costs in this important industrial sector.

A novel type of adsorbent (CM) was synthesized by cellulose modified with maleic anhydride to remove heavy metal ions and organic dyes in this work. The synthesized adsorbent was characterized by FTIR, SEM, TGA and XRD. The degree of carboxyl group of CM was found to be 2.7 mmol g -1 by the titration method. The adsorption of Hg(II) ions as heavy metal ions while basic fuchsine, methylene blue and crystal violet as organic dyes by CM was investigated. The influence of different experimental parameters such as pH, contact time, temperature on removal process was evaluated. The results indicated that the CM has a good adsorption capacity for Hg(II). The maximum adsorption capacity of Hg(II) was found to be 172.5 mg g -1 , and the adsorption process was described by Freundlich isotherm model of adsorption well. The process of basic fuchsine, methylene blue and crystal violet adsorbed by CM was also studied and the adsorption removal rate of those organic dyes was 88.10, 98.47 and 92.85 % under the optimum conditions, respectively. The adsorption process was depicted by the Langmuir isotherm model more correctly.

“…However, a major challenge in the modification jute fiber (MJF) production is how to improve its adsorption capacity greatly and rapidly. Microwave (MW) heating, as a high efficient heating method, has widely applied in modifications (Li et al, 2011;Wang et al, 2014). The major advantages of MW are rapid heat transfer, energy saving and automatic control (Liu et al, 2003).…”
