摘要
以羟基磷灰石、HAP-100、HAP-200、HAP-300和HAP-400 (Taihei Chemical Industrial Co.)分别制备的四种经Fe(III)处理的羟基磷灰石(HAP-100、HAP-200、HAP-300和HAP-400)为原料，对广泛使用的除草剂阿特拉津(ATZ)进行了非均相光fenton反应研究，并与市售的Fe(III)化合物fe2o3、fepo4•2h2o和FeOOH进行了比较。在Fe(III)-羟基磷灰石中，HAP-400-Fe表现出最有效的催化活性(ATZ消耗90%)，几乎等于fepo4•2h2o。尽管TOC-TN、去乙基化、去异丙基化和oh取代的ATZ都没有检测到ATZ的矿化，并且通过使用HAP-400-Fe对ATZ光- fenton反应产生的溶液进行LC-MS分析，发现了相关的氧化降解产物。
HETEROGENEOUS PHOTO-FENTON REACTION OF A HERBICIDE ATRAZINE BY USING Fe(III)-TREATED HYDROXYAPATITES
: A widely-used herbicide, atrazine (ATZ), was investigated in heterogeneous photo-Fenton reaction using four Fe(III)-treated hydroxyapatites, HAP-100-Fe, HAP-200-Fe, HAP-300-Fe, and HAP-400-Fe, which were prepared from hydroxyapatites, HAP-100, HAP-200, HAP-300, and HAP-400, respectively (Taihei Chemical Industrial Co.), and compared with commercially available Fe(III) compounds, Fe 2 O 3 , FePO 4 •2H 2 O, and FeOOH. Among the Fe(III)-hydroxyapatites, HAP-400-Fe indicated the most efficient catalytic activity (ATZ consumption, 90%), which was almost equal to FePO 4 •2H 2 O. Although mineralization of ATZ was never detected by TOC-TN, deethylated, deisopropylated, and OH-substituted ATZs, and related oxidative degradation products were identified from LC-MS analysis of the resulting solution of ATZ photo-Fenton reaction using HAP-400-Fe.
