| Summary: | Chitosan and cellulose are ubiquitous and biodegradable polysaccharides. With the presence of amino (-NH2) and hydroxyl (-OH) groups, chitosan and cellulose are introduced as supporting materials for metal nanoparticles. This study aimed to investigate and compare the physicochemical properties of nickel nanoparticles (NiNPs) immobilized on two different substrates, which are pristine filter paper (FP) and chitosan-filter paper (CS-FP). Their photodegradation efficiency of methylene blue (MB) under UV irradiation were determined by parameters such as the initial concentration of MB, the photocatalyst dosage, and the concentration of the reducing agent. The presence of chitosan impact on the composition of NiNPs was revealed through the application of SEM-EDX and FTIR analysis. Additionally, increasing the photocatalyst dosage from 0.2 g to 0.6 g resulted in the photocatalytic degradation of MB by NiNPs/FP and NiNPs/CS-FP increasing from 42.8 % to 68.7 % and 22.4 % to 47.6 %, respectively. In addition, it was demonstrated that the photodegradation efficiency of NiNPs/FP and NiNPs/CS-FP was decreased from 67.4 % to 62.8 % and 61.4 % to 38.7 %, respectively, by raising the initial concentration of MB (10-50 ppm). As the reducing agent concentration (0-0.5 M) increases, the photodegradation efficiency of NiNPs/FP and NiNPs/CS-FP increase from 24.4 % to 98.2 % and 4.6 % to 64.4 %, respectively. It can be concluded that both NiNPs/FP and NiNPs/CS-FP have good points in different aspects. Taken together, the results of this study may contribute to an ideal nanoparticle immobilization matrix. Consequently, its application in the photodegradation of dyes may achieve the third goal of Sustainable Development Goal (SDG) 6, which is to increase global water recycling and safe reuse by minimizing the amount of untreated wastewater globally. |
