Heterogeneous photocatalytic degradation of anionic dye on polyaniline/microcrystalline cellulose composite

Abstract: The development of novel polymeric composites, especially those based on conductive polymers has attracted a consider-able attention due to their applications in a wide range of fields. This study focuses on one of these biocomposites based on polyaniline Pani and a biopolymer (microcrystalline cellulose MCC), synthesized by in-situ polymerization of aniline using ammonium persulfate (APS) as oxidant at room temperature. Firstly, different amounts of MCC were dispersed in HCl solu-tion with aniline monomer und… Show more

“…The first-order kinetic model of LH assumes that the number of catalytic sites will not be a limiting factor and the rate of degradation of the pollutant is proportional to its concentration [25]. Thereby, the linear correlation between Ln (COD 0 /COD) and the irradiation time, confirmed the hypothesis that the photocatalytic degradation of the pesticide on the titaniferous sand, follows the LH model well and is of the first order.…”

“…Azo dyes, and in general organic synthetic dyes, are other environmental pollutants with carcinogenicity depending on their structural characteristics and degradation mechanism. ,, For example, common degradation intermediates of azo dyes are aromatic amines with a common carcinogenic future. Further, azo dyes can alter biochemical markers, provoking allergic reactions. ,, …”

“…CNC/LC and CNC/LCP hybrid materials have shown a potential to replace plastics and petroleum-based materials owing to their inherent ability to decompose under the activity of light (photodegradation) and enzymes (biodegradability). The rate of degradation is influenced by factors such as the degree of crystallinity, molecular weight of the CNCs and LCs or LCPs, concentration of the filler material, and the morphology and water uptake ability of the material. , Similar studies have linked the time and temperature of decomposition to the degradation behavior of CNCs. The aspect ratio of the cellulosic material is another key factor that affects the thermal stability of these hybrid platforms.…”
