The targeted chromatographic achievements of eight NSAA viz. aniline, 4-aminoazobenzene, azobenzene, 4-aminobiphenyl, sudan-1, 1-napthylamine 4-methylimidazole and p-toluidine in degradation and stability samples of Sunset yellow and Ponceau 4R were exercised using validated HPLC–PDA method. The chromatographic retention of selected peaks were successfully achieved on Hyper Sil gold C8 Stationary phase (250 mm × 4.6 mm i.d., 5 µm particle size) with ammonium acetate buffer (pH 4.0) as mobile phase A and combination of acetonitrile and methanol as organic phase (mobile phase B) in gradient mode. The optimised analytical method was specific, accurate &amp; precise and detector signal was observed linear in the range of 50–10,000 ng.mL⁻¹ for all aromatic amines. The stability of selected azo dyes was observed for three months at refrigerated (2–8° C) and at room temperature (25 °C) both in solid state and in liquid state. The degradation and stability data were mapped to reveal the essential pattern of carcinogenic aromatic amines formation using unsupervised learning approaches to discriminate the NSAA formation under forced degradation conditions and stability of selected dye/s at various storage conditions. The heatmap and PCA reveal that the stability of selected azo dyes at room temperature and in refrigerated storage conditions could be correlated with formation of 4-aminoazobenzene, azobenzene, 4-aminobiphenyl, sudan-1, 1-napthylamine and p-toluidine. As per regulatory guidelines, aniline formation should be observed during storage period, as contrast to traditional consideration of aniline as major NSAA, whose <i>occurrence</i> is in-general calculated as total NSAA formation, it was not observed in any storage sample.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":676,"journal":{"name":"Journal of the Iranian Chemical Society","volume":"22 2","pages":"383 - 396"},"PeriodicalIF":2.2,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143184632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a DES-supported catalyst was prepared.

The physicochemical properties of the catalyst were deeply assessed by using TGA-MS, XRD, SEM–EDX, FTIR, UV–vis-DRS and surface charge (pH &lt;sub&gt;PZC&lt;/sub&gt;) technique. Here, several methods have been explored to estimate the crystallite size and strain in the CeO&lt;sub&gt;2&lt;/sub&gt;-500 using X-ray peak profile analysis. XRD results revealed the formation of crystalized face-centered cubic fluorite-type CeO&lt;sub&gt;2&lt;/sub&gt; phase with the special group Fm-3 m (N°.225). The results of crystallite size and Microstrain estimated by various methods for the CeO&lt;sub&gt;2&lt;/sub&gt;-500 sample demonstrate that the Size-Strain Plot (SSP) and Halder–Wagner (H–W) methods are more accurate, the values of &lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; (&lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0.9975) are for both models. In comparison with Scherrer, W–H and SSP methods, H–W model exhibited a minimum of microstrain (&lt;i&gt;ε&lt;/i&gt; = 0.000225) which indicate the narrower size distribution, trivial strains and the presence of defects and size-shape isotropy in the CeO&lt;sub&gt;2&lt;/sub&gt;-500 environment. Further, the estimated higher value of strain (&lt;i&gt;ε&lt;/i&gt;&lt;b&gt; = &lt;/b&gt;0.109) for SSP method may be accredited to the lattice dislocations. All the methods provide crystallite sizes within 10 nm for the as synthesized CeO&lt;sub&gt;2&lt;/sub&gt; NPs, excluding for LSLM model which resulted in a crystallite size of 22.72 nm, which proved to be invalid crystal.
