| 1 | Identification of pesticide residue level in lettuce based on hyperspectra and chlorophyll fluorescence spectra显示文摘Fast identification of pesticide residue level in lettuce leaves plays a key role in the test of food safety.In order to identify the different concentrations pesticide residues of lettuce leaves in a fast and nondestructive way,the hyperspectra coupled with chlorophyll fluorescence spectra was used in this research.Transmission electron microscopy(TEM)was used to identify the microstructure changes of lettuce leaves under different concentrations of dimethoate residue.Besides,a method involving wavelet transform and MD-MCCV algorithm(WT-MD-MCCV)was developed for identifying the optimal wavelengths of the spectral data.The hyperspectra and chlorophyll fluorescence spectra data of 150 lettuce leaf samples at five different concentrations of pesticide residues were obtained using hyperspectral data acquisition device and Cary Eclipse Fluorescence Spectrophotometer.The combination of Savitzky-Golay(SG)algorithm and SNV algorithm(SG-SNV)preprocessing algorithms was used to preprocess the raw spectra.In addition,Principal Component Analysis(PCA),Successive Projections Algorithm(SPA)and wavelet transform coupled to MD-MCCV algorithm(WT-MD-MCCV)were applied to identify the optimal wavelengths of raw spectra including hyperspectra data,chlorophyll fluorescence spectra data and hyperspectra coupled with chlorophyll fluorescence spectra data.Support vector regression(SVR)was applied to build the prediction models based on preprocessed spectra feature in characteristic wavelengths coupled with different spectral data.The results showed that with the increase of the concentration of dimethoate pesticide spraying,lettuce chloroplast number of osmiophilic particles increased and the starch granules decreased.Besides,the intercellular space of lettuce leaves increased gradually,with the increase of dimethoate concentration.Different concentrations of pesticide residues of lettuce in the near infrared and fluorescence spectrum have a certain difference.In addition,the related parameters of the three preferably prediction models were Rp 2=0.956 and RMSEP=0.018,Rp 2=0.937 and RMSEP=0.161,Rp 2=0.987 and RMSEP=0.005,respectively,using WT-MD-MCCV algorithm combined with hyperspectra data,chlorophyll fluorescence spectra data and hyperspectra coupled to chlorophyll fluorescence spectra data.WT-MD-MCCV algorithm combined with hyperspectra and chlorophyll fluorescence spectra data performed best among the nine SVR models and the hyperspectra coupled with chlorophyll fluorescence spectra can be used to identify the pesticide residue level in lettuce leaves. | Sun Jun Zhou Xin Mao Hanping Wu Xiaohong Zhang Xiaodong Gao Hongyan | 2016 | International Journal of Agricultural and Biological Engineering2016，9，6： | 2 |

| 9 | Physicochemical and adsorption properties of biochar from biomass-based pyrolytic polygeneration:effects of biomass species and temperature显示文摘Biochar obtained from a biomass pyrolytic polygeneration technology exhibits great potential as an adsorbent,because of its renewability,porosity and desirable surface chemical properties.Pyrolysis temperature and feed are important elements in the preparation of biochar.Thus,the effects of these factors on the physicochemical properties of biochar were investigated in this study.The adsorption of biochar was evaluated using water,CO_(2),phenol,and methylene blue(MB)as adsorbates.The correlation between adsorption capacity and physicochemical properties was determined using the Pearson correlation.Results indicated that temperature could significantly affect the structure of biochar.The effects of biomass species were also noticeable as well.The number of macropores and their contribution to the total surface area for cotton stalk,bamboo,and rapeseed stalk increased with an increase in temperatures,meanwhile,the number of micropores decreased at high tem-peratures.At the same temperature,the macropore,mesopore,and micropore components of biochar produced by different species were markedly different.The water adsorption and CO_(2) adsorption of biochar were close to those of commercial activated carbon(AC),whereas the adsorption capacity of untreated biochar on phenol and MB was less than that of AC.Porosity exerted more significant effects on the adsorption capacity of biochar,compared with functional groups.The surface area of the micropores exhibited a significant positive correlation with the adsorption of CO_(2),phenol,and MB.The hydroxyl group was positively correlated with water adsorption. | Zhang Xiong Zheng Huanhuan Wu Jing Chen Wei Chen Yingquan Xuezhi Gao Yang Haiping Chen Hanping | 2021 | Biochar2021，3，4： | 1 |
