Therefore, rapid detection of PAHs is critical for controlling pollution and protecting the ecology. Considering the advantages of surface\u2010enhanced Raman spectroscopy (SERS), a simple and reliable SERS method was proposed in this work for detecting PAHs in water. Three chemicals, namely NaCl, KBr, and KI, were chosen to modify Ag nanoparticles (NPs) for phenanthrene (Phe) detection, and Ag NPs modified with KBr (Ag\u2010Br NPs) showed the best SERS response. The mixing sequence and the concentration of KBr were optimized. The addition order of mixing KBr and Ag NPs before Phe solution was the best sequence, and the optimal concentration of KBr was 20\u2009mM. Under optimal conditions, the limits of quantification for Phe, pyrene (Pyr), and anthracene (Ant) were 10<jats:sup>\u22126<\/jats:sup>\u00a0M, 10<jats:sup>\u22127<\/jats:sup>\u00a0M, and 10<jats:sup>\u22127<\/jats:sup>\u00a0M, respectively. Mixed PAHs (Phe, Pyr, and Ant) in spiked water samples were identified and quantified successfully. The proposed method has good application prospects in environmental pollution monitoring.<\/jats:p>","DOI":"10.1002\/bio.4329","type":"journal-article","created":{"date-parts":[[2022,7,11]],"date-time":"2022-07-11T10:59:25Z","timestamp":1657537165000},"page":"1541-1546","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Halogen ion\u2010modified silver nanoparticles for ultrasensitive surface\u2010enhanced Raman spectroscopy detection of polycyclic aromatic hydrocarbons"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9588-7112","authenticated-orcid":false,"given":"Dongmei","family":"Wang","sequence":"first","affiliation":[{"name":"Faculty of Geosciences and Environmental Engineering Southwest Jiaotong University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyi","family":"Zhu","sequence":"additional","affiliation":[{"name":"Faculty of Geosciences and Environmental Engineering Southwest Jiaotong University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binyu","family":"Hui","sequence":"additional","affiliation":[{"name":"Faculty of Geosciences and Environmental Engineering Southwest Jiaotong University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5710-3156","authenticated-orcid":false,"given":"Zhengjun","family":"Gong","sequence":"additional","affiliation":[{"name":"Faculty of Geosciences and Environmental Engineering Southwest Jiaotong University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meikun","family":"Fan","sequence":"additional","affiliation":[{"name":"Faculty of Geosciences and Environmental Engineering Southwest Jiaotong University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envint.2013.07.019"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2018.01.262"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17041363"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1006\/clim.2000.4934"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/bio.834"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00204-014-1296-5"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11802-019-3911-9"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.saa.2019.117783"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpolbul.2004.02.011"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fct.2009.01.011"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2010.09.025"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s41664-021-00192-x"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tifs.2021.01.058"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/bio.4268"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1039\/c2jm34686a"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac503672f"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/bio.3382"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1039\/C9AN01540J"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4RA00121D"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/am5087209"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.matpr.2017.07.041"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1002\/bio.3796"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5AY02540K"},{"key":"e_1_2_8_25_1","first-page":"8330702","volume":"2022","author":"Zhang Q.","year":"2022","journal-title":"Comput.
