Facile and single step method was used for synthesis of green coating based on mandarin peel and chitosan. As, the mandarin peel as fruit waste material was dried, grinded and directly dispersed in chitosan solution producing new green coating composite and then coated on textile fabrics. The mass loadings of green mandarin peel powder was varied on 20-70 wt% and optimized. Thermal stability of coated textile fabrics was enhanced and char yield was improved compared to uncoated one. The charring effect of mandarin peel powder coated samples was significantly enhanced anticipating good flame retardancy effect. The Maximum break loading of the coated textile fabrics was improved achieved 35% improvement compared to uncoated sample reflecting reinforcement of textile fabrics. The interaction between the renewable coating and textile was evaluated. The morphology of uncoated and coated textile fabrics was studied using microscopic technique. Additionally, based on thermal properties of mandarin peel powder it could be promising flame retardant for textile fabrics. This study open new avenues for finishing textile fabrics with enhanced thermal, flame retardancy and mechanical properties with cost-effective and renewable green and effective coating.","PeriodicalId":23851,"journal":{"name":"World Academy of Science, Engineering and Technology, International Journal of Chemical and Molecular Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90202549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives involved determining the effects of the basic adsorption parameters namely, agitation time, adsorbent dosage, adsorbents particle size, adsorbate loading concentrations and initial pH, on the adsorption process as well as characterizing the adsorbents by determining their physicochemical properties, functional groups responsible for the adsorption process using Fourier Transform Infrared (FTIR) spectroscopy and surface morphology using scanning electron microscopy (SEM) coupled with energy dispersive X - ray spectroscopy (EDS). The adsorption behaviours of the materials were tested against Langmuir, Freundlich, Temkin, Dubinin Radushkevic and Harkins Jura isotherm models. Percent adsorption increased with increase in agitation time (5 - 240 minutes), adsorbent dosage (100- 500mg), initial concentration (100-300mg/L), and with decrease in particle size (≥75μm to ≤300μm) of the adsorbents. Both processes are dye pH-dependent, increasing or decreasing percent adsorption in acidic (2-6) or alkaline (8-12) range over the studied pH (2-12) range. From the experimental data the Langmuir's separation factor (RL) suggests unfavourable adsorption for all processes, Freundlich constant (nF) indicates unfavourable process for CR and MO adsorption; while the mean free energy of adsorption �� , calculated from Dubinin-Radushkevich equation suggest a physical adsorption. Reduction in band intensities and vibrational changes observed in FTIR spectra indicate possible involvement of carbonyl (-C=O), carboxyl (-COOH) and hydroxyl (-OH) functional groups on the adsorbents' surfaces during the adsorption and interaction with the sulfonic acid groups (-SO3Na) on the dye molecules. The difference in irregular and porous texture surface morphology of fresh and dye- loaded adsorbent characterized the adsorption of the dyes by the adsorbent. While EDS analysis indicates that adsorbent consist of mainly C and O, and small amounts of, Ca, Mg, K, P and S. The result of this study shows that neem leaves are potential alternative low-cost adsorbents for the effective removal of Congo red (CR) and methyl orange (MO), from aqueous solutions.
