“…This is due to the success of the removal of the other untreated cellulose materials.Results of EDX analysis for MCC, showed that carbon and oxygen are the main components, however, silica and calcium were detected at lower levels. Similar results were reported by Chin et al (2013) on MCC extracted from RS, Kunusa et al and (2018) on MCC extracted from corncobs with 6% NaOH alkaline treatment.…”

R EUSING wastewater as an additional resource of water in Egypt always be facing by high load of contaminants, especially potentially toxic elements (PTEs). Sorption of PTEs is one of the technologies used for treatment wastewater. Cellulose derived materials, like microcrystalline cellulose, can be used for removal of PTEs. In this study, microcrystalline cellulose prepared from rice straw with an eco-friendly method and tested for Pb, Cd, and Cu removal from artificial contaminated water. Factors affecting metal ions removal were also investigated. Obtained results showed that the removal efficiency of the PTEs was 94, 72, and 89% for Pb, Cd, and Cu, respectively at 10 mg L -1 of microcrystalline cellulose. Removal of Cd and Cu decreased with increasing of initial concentration up to 200 mg L -1 , however, for Pb the removal efficiency was near 90% till initial concentration 150 mg L -1 . In summary, the prepared microcrystalline cellulose were shown as promising adsorbents can assist PTEs from contaminated wastewater.

Different synthesized materials either irradiated or non-irradiated were examined in the laboratory to identify its characteristics as efficient absorbers in removing Pb, Cd, and Cu from contaminated water. Bio-based polymers are gaining overwhelming interest and recognition worldwide due to the health, safety, and environmental concerns associated with the conventional synthetic polymers. These bio-based polymers are renewable, biodegradable, and environmentally-friendly. The characterization analysis confirmed the successful synthesis of the investigated materials. The processing of rice straw was effective in removing silica and hemicellulose and leaving microcrystalline cellulose with an accepted level of purification. Vulcanized used fried oil was efficient to produce polysulphide polymer. Results gained from this laboratory work indicated that irradiated sorbents were more effective on the sorption of Pb, Cd and Cu especially those exposed to lower doses compared to the non-irradiated sorbents. At a high gamma ray dose (50 KGy), some sorbents showed inhabitation effect on sorption behavior and also removal efficiencies. It can be concluded that rice straw and fried oil can be used to synthesize suitable sorbents to remove contaminants from the water, and gamma radiation treatment was effective to improve contaminants removal.

“…Chin et al had reported on the extraction of microcrystalline cellulose from rice straw via cyclic alkaline and bleaching treatment, and its incorporation in PVA biocomposite films through solution casting process. 4 The tensile strength and young modulus of the films improved up to 7.5 wt% with the microcrystalline cellulose addition, attributed to the high surface area of filler, uniform dispersion and good interfacial adhesion.…”

The utilisation of waste materials in polymer matrices is gaining attraction due to the growing environmental awareness. In this work, eggshells waste was added into polyvinyl alcohol to produce biocomposite films via solution casting method. In order to enhance the properties of the biocomposite, glutaraldehyde (GA) was incorporated as the crosslinking agent. The effects of GA content on the biocomposite were evaluated in terms of its tensile properties, physical properties and biodegradability. From the tensile test, the optimum GA content was found to be 2 phr as portrayed by the highest tensile strength at this GA content. Further addition of GA deteriorated the mechanical properties of the biocomposite. On the other hand, the water absorption, water vapour transmissibility and biodegradability (via natural weathering and soil burial) of the biocomposite films decreased with GA addition.
