开发了一种利用臭氧去除蔬菜中农药残留的新型机器。这种家用蔬菜清洗机由密闭式清洗室、臭氧发生器、水循环泵和氧化还原电位电极组成。用白菜和青菜两种蔬菜和氯菊酯(trans-3-(2，2-dichlorovinyl)-2，2-dimethylcyclopropane-carboxylate)，氯氟草隆((1-[3，5-dichloro-4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenyl]-3-(2，6-二氟苯甲酰基)尿素和百菌清(四氯间苯二甲腈)3种农药进行药效试验。用泵循环清洗15min，可去除51%的百菌清和53%的百菌清。当臭氧产生率为250 mg/h时，百菌清和百菌清的去除效率分别为60%和55%，比泵循环提高2~9个百分点。当臭氧产生率为500 mg/h时，百菌清和百菌清的去除效率分别为75%和77%，比泵循环提高了24%。臭氧处理后，农药残留量全部达到《食品中农药残留限量标准》。(C)2012爱思唯尔有限公司。保留所有权利。
A novel machine was developed to remove pesticide residues from vegetables using ozone. This domestic-scale vegetable cleaner consists of a closed cleaning chamber, an ozone generator, a water recirculation pump, and an oxidation-reduction potential (ORP) electrode. Two vegetables, Chinese white cabbage and green-stem bok choy, and three pesticides, permethrin (trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-carboxylate), chlorfluazuron (1-[3,5-dichloro-4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenyl]-3-(2, 6-difluorobenzoyl) urea), and chlorothalonil (tetrachloroisophthalonitrile) were used in tests. Cleaning for 15 min with pump recirculation removed 51% of chlorfluazuron and 53% of chlorothalonil. When the ozone production rate was 250 mg/h, removal efficiencies were 60% for chlorfluazuron and 55% for chlorothalonil, increases of 2-9% over pump recirculation only. When the ozone production rate was 500 mg/h, removal efficiencies were 75% for chlorfluazuron and 77% for chlorothalonil; increases of 24% over pump recirculation only. After the ozone treatment, all the pesticide residuals met the Standards for Pesticide Residue Limits in Foods. (C) 2012 Elsevier Ltd. All rights reserved.
