Mishonga yezvipembenene makemikari anoshandiswa kuuraya zvipembenene, kusanganisira tumbuyu, makonzo, fungi uye zvinokuvadza zvinomera (sora).Pamusoro pezvo, dzinoshandiswa zvakare muhutano hweveruzhinji kuuraya zvinotakura zvirwere zvakaita seumhutu.Nekuti inogona kukonzera chepfu kune zvimwe zvipenyu, kusanganisira vanhu, mishonga yezvipembenene inofanirwa kushandiswa zvisina njodzi uye kubatwa nemazvo1.
Kubasa, kubatwa nemishonga yezvipembenene kumba kana mugadheni kunogona kukonzera kubatwa nemishonga yezvipembenene, semuenzaniso kuburikidza nechikafu chine utachiona.WHO inoongorora humbowo uye inoisa miganho yezvisaririra inozivikanwa pasi rose kudzivirira vanhu kubva kunjodzi dzehutano dzinogona kukonzerwa nemishonga yezvipembenene.2
Reversed-phase high performance liquid chromatography (HPLC) inowanzo shandiswa kufungidzira kuungana kwezvinhu zvinoshanda mumishonga yezvipembenene.Zvisinei, rudzi urwu rwechromatography runoda kushandiswa kwemishonga ine chepfu, uye inopedza nguva uye yakanyatsodzidziswa vashandi, zvichiita kuti mari yakawanda yekuongorora nguva dzose.Kushandisa inoonekwa padhuze ne infrared spectroscopy (Vis-NIRS) pachinzvimbo cheHPLC kunogona kuchengetedza nguva nemari.
Kuedza kushanda kweVis-NIRS pachinzvimbo cheHPLC, 24-37 mishonga yezvipembenene ine inozivikanwa inoshanda makomisheni yakagadziriswa yakagadzirwa: abamectin EC, amimectin EC, cyfluthrin EC, cypermethrin, uye glyphosate.Ongorora kuwirirana pakati pekuchinja.Spectral data uye referensi kukosha.
NIRS RapidLiquid analyzer inoshandiswa kuwana iyo spectrum yayo yese wavelength renji (400-2500 nm).Muenzaniso unoiswa mubhodhoro regirazi rinoraswa rine dhayamita ye4 mm.Vision Air 2.0 Complete software inoshandiswa kuunganidza data uye manejimendi pamwe nekuwedzera nzira yekuvandudza.Chikamu chidiki-diki (PLS) regression chakaitwa pamuenzaniso wega wega wakaongororwa, uye mukati-muchinjiko-kusimbisa (kusiya imwe kunze) yakashandiswa kusimbisa kushanda kwehuwandu hwemhando yakatorwa panguva yekuvandudza nzira.
Mufananidzo 1. Iyo NIRS XDS RapidLiquid analyzer inoshandiswa pakutsvaga data spectral pamusoro pehuwandu hwe400 nm kusvika 2500 nm.
Kuti kuverengera komputa imwe neimwe mumushonga, modhi inoshandisa zvinhu zviviri yakamiswa, ine calibration standard error (SEC) ye0.05% uye cross-validation standard error (SECV) ye0.06%.Pamushonga wega wega unoshanda, iyo R2 kukosha pakati peiyo yakapihwa kukosha kukosha uye yakaverengerwa kukosha ndeye 0.9946, 0.9911, 0.9912, 0.0052, uye 0.9952, zvichiteerana.
Mufananidzo 2. Raw data spectra yemasampuli gumi nemasere emushonga wezvipembenene ane abamectin yakawanda pakati pe1.8% ne3.8%.
Mufananidzo 3. Correlation graph pakati pezvinyorwa zveabamectin zvakafanotaurwa neVis-NIRS uye kukosha kwekutarisa kwakaongororwa neHPLC.
Mufananidzo 4. The raw data spectra ye 35 pesticide samples, umo mutsara wehuwandu hweamomycin ndeye 1.5-3.5%.
Mufananidzo 5. Correlation graph pakati pe amimectin zvinyorwa zvakafanotaurwa neVis-NIRS uye kukosha kwekutsvaga kwakaongororwa neHPLC.
Mufananidzo 6. Raw data spectra ye24 mishonga yezvipembenene ine cyfluthrin concentrations ye2.3-4.2%.
Mufananidzo 7. Correlation graph pakati pezvinyorwa zve cyfluthrin zvakafanotaurwa neVis-NIRS uye kukosha kwekutsvaga kwakaongororwa neHPLC.
Mufananidzo 8. The raw data spectra ye27 pesticide samples ine cypermethrin concentration ye4.0-5.8%.
Mufananidzo 9. Correlation graph pakati pezvinyorwa zve cypermethrin zvakafanotaurwa neVis-NIRS uye kukosha kwekutsvaga kwakaongororwa neHPLC.
Mufananidzo 10. The raw data spectra ye 33 pesticide samples ine glyphosate concentration ye21.0-40.5%.
Mufananidzo 11. Girafu yekubatanidza pakati pezvinyorwa zveglyphosate zvakafanotaurwa neVis-NIRS uye kukosha kwekutarisa kwakaongororwa neHPLC.
Aya akanyanya kuwirirana kukosha pakati pekukosha kwereferensi uye kukosha kwakaverengerwa uchishandisa Vis-NIRS inoratidza kuti inzira yakavimbika uye inokurumidza kudzora mhando yemishonga yezvipembenene kana ichienzaniswa neyagara ichishandiswa HPLC nzira.Naizvozvo, Vis-NIRS inogona kushandiswa seimwe nzira kune yakakwirira-inoshanda liquid chromatography yenguva dzose yekuongorora mushonga wezvipembenene uye inogona kuchengetedza nguva nemari.
