The resulting mixture was subjected to comprehensive characterization using a range of analytical techniques, including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The newly synthesized PF\u2013PYZ material effectively removes Cr\u00ad(VI) ions. Notably, a substantial elimination efficiency of 96% was achieved after just 60 min of contact time. The strategic incorporation of pyrazole (PYZ) as the principal functionalizing agent contributed to this exceptional performance. Notably, the functionalized PYZ sites were strategically positioned on the surface of PF, rendering them readily accessible to metal ions. Through rigorous testing, the optimal sorption capacity of PF\u2013PYZ for Cr\u00ad(VI) ions was quantified at 0.872 mmol Cr\u00ad(VI)\/g, highlighting the material\u2019s superior adsorption capabilities. The practical utility of PF\u2013PYZ was further established through a reusability test, which demonstrated that the chromate capacity remained remarkably stable at 0.724 mequiv Cr\u00ad(VI)\/g over 20 consecutive cycles. This resilience underscores the robustness of the resin, indicating its potential for repeated regeneration and reuse without a significant capacity loss. Our work presents a novel approach to functionalizing phenol-formaldehyde with pyrazole, creating PF\u2013PYZ, a highly efficient material for removing Cr\u00ad(VI) ions. The compound\u2019s facile synthesis, exceptional removal performance, and excellent reusability collectively underscore its promising potential for various water treatments, especially oil field and environmental remediation applications.<\/jats:p>","DOI":"10.1021\/acsomega.3c05432","type":"journal-article","created":{"date-parts":[[2024,2,25]],"date-time":"2024-02-25T09:52:00Z","timestamp":1708854720000},"page":"10090-10098","source":"Crossref","is-referenced-by-count":3,"title":["Phenol-Formaldehyde\/Pyrazole Composite: Synthesis,\nCharacterization, and Evaluation of its Chromate Removal Efficiency"],"prefix":"10.1021","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0253-5714","authenticated-orcid":true,"given":"Moaz M.","family":"Abdou","sequence":"first","affiliation":[{"name":"Egyptian Petroleum Research Institute , Nasr City , ,","place":["Cairo, Egypt, 11727"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dalia M.","family":"Abbas","sequence":"additional","affiliation":[{"name":"Egyptian Petroleum Research Institute , Nasr City , ,","place":["Cairo, Egypt, 11727"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enas Arafa","family":"Ismail","sequence":"additional","affiliation":[{"name":"Egyptian Petroleum Research Institute , Nasr City , ,","place":["Cairo, Egypt, 11727"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Zahran","sequence":"additional","affiliation":[{"name":"Egyptian Petroleum Research Institute , Nasr City , ,","place":["Cairo, Egypt, 11727"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Abu-Rayyan","sequence":"additional","affiliation":[{"name":"Applied Science Private University , , ,","place":["Amman, Jordan, 11931"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nawal H.","family":"Bahtiti","sequence":"additional","affiliation":[{"name":"Applied Science Private University , , ,","place":["Amman, Jordan, 11931"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed H.","family":"Ragab","sequence":"additional","affiliation":[{"name":"King Khalid University , , ,","place":["Abha, Saudi Arabia, 61413"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hussah A.","family":"Alshwyeh","sequence":"additional","affiliation":[{"name":"Imam Abdulrahman Bin Faisal University , , 1982, ,","place":["Dammam, Saudi Arabia, 31441"]},{"name":"Imam Abdulrahman Bin Faisal University , , 1982, ,","place":["Dammam, Saudi Arabia, 31441"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abeer A.","family":"Hassan","sequence":"additional","affiliation":[{"name":"King Khalid University , , ,","place":["Abha, Saudi Arabia, 61413"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdel-Ghany A.","family":"Soliman","sequence":"additional","affiliation":[{"name":"National Institute of Oceanography and Fisheries , ,","place":["Cairo, Egypt, 11796"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2024,2,25]]},"reference":[{"key":"2026081709113495500_cit1","doi-asserted-by":"publisher","first-page":"141","DOI":"10.1016\/j.seppur.2015.11.039","article-title":"Heavy Metal Removal from Aqueous Solution by Advanced\nCarbon Nanotubes: Critical Review of Adsorption Applications","volume":"157","author":"Ihsanullah","year":"2016","journal-title":"Sep.
