Chowunikira chamafuta a UV chimagwiritsa ntchito n-hexane ngati chotsitsa ndipo chimagwirizana ndi zofunikira za muyezo watsopano wadziko lonse "HJ970-2018 Determination of Water Quality Petroleum by Ultraviolet Spectrophotometry".
mfundo yogwirira ntchito
Pansi pa pH ≤ 2, zinthu zamafuta zomwe zili mu zitsanzo zimachotsedwa ndi n-hexane. Chotsitsacho chimakhala ndi madzi amthupi ndi anhydrous sodium sulfate, kenako amadsorbed ndi magnesium silicate kuchotsa zinthu za polar monga mafuta anyama ndi masamba. Kutentha kumayesedwa mu dera la ultraviolet. Mafuta amafuta amafuta komanso kuyamwa kwake kumagwirizana ndi lamulo la Lambert-Beer, potero amasanthula kuchuluka kwamafuta m'madzi.
Kuchuluka kwa ntchito
Oyenera kutsimikiza kwa petroleum m'madzi apamwamba, pansi pamadzi ndi m'nyanja. Amagwiritsidwa ntchito kwambiri m'machitidwe owunikira zachilengedwe, mafakitale a petrochemical, makoleji ndi mayunivesite, mabungwe ofufuza zasayansi, malo ochitira zimbudzi, malo osungira madzi ndi hydrology, zomera zamadzi, petrochemicals, kupanga mapepala, mankhwala, zitsulo, ulimi Kuwunika zachilengedwe ndi mafakitale ena.
Kusiyana kwake
Mitundu yogwiritsira ntchito njira ya UV ndi njira ya infrared ndizosiyana. Njira ya infrared ili ndi malire ozindikira kwambiri ndipo ndiyoyenera kudziwa mafuta (mafuta amafuta, nyama ndi masamba) m'chimbudzi. Njira ya UV ili ndi mphamvu zambiri komanso malire otsika ozindikira ndipo ndi oyenera madzi apansi ndi pansi. ndi kutsimikiza kwa petroleum m'madzi a m'nyanja.
Njira ya infrared: Njira ya infrared imakhala ndi chidwi chachikulu, zotsatira zolondola komanso zochulukira, ndipo imagwiritsa ntchito tetrachlorethylene ngati chochotsa m'malo mwa carbon tetrachloride yomwe imawononga ozoni.
Njira ya ultraviolet: Njira ya ultraviolet imakhala ndi mphamvu zambiri ndipo ndiyoyenera kutsimikizira mafuta a petroleum m'madzi apamwamba, pansi pa madzi ndi m'nyanja. Muyezowu umapereka chitsimikiziro chomveka bwino chaubwino komanso zofunikira zowongolera, zomwe zitha kutsimikizira zasayansi komanso kulondola kwazomwe zimayang'anira pakugwiritsa ntchito njirayo.
LH-OIL336, chowunikira chamafuta a UV chodziyimira pawokha ndi Lianhua, chimagwirizana ndi njira ndi mfundo zaposachedwa, chimagwiritsa ntchito n-hexane ngati chotsitsa, ndipo ndichoyenera kutsimikiza mafuta amafuta m'madzi apansi, pansi pamadzi ndi m'madzi a m'nyanja.
Lianhua LH-OIL336 UV mita yamafuta ndi yosavuta kugwiritsa ntchito, imakhala yolondola bwino, yokhudzika kwambiri komanso magwiridwe antchito okhazikika. Itha kukwaniritsa zosowa zosiyanasiyana zamakasitomala ndikupulumutsa nthawi yamakasitomala pakuyesa kwamadzi. Muyeso wachindunji wa chida choyezera mafuta ichi ndi 0.04-1ppmm. Ili ndi 7-inch high-definition touch screen, imagwiritsa ntchito 20mm quartz cuvette poyeza mtundu, ndipo ili ndi makina osindikizira omwe amatha kusunga zidutswa 5,000 za deta. Ili ndi digiri yayikulu yodzichitira yokha, ndiyosavuta komanso yachangu, komanso kugwiritsa ntchito n-hexane popeza chotsitsacho chimakhalanso chokonda zachilengedwe komanso chotetezeka. Ilinso ndi ntchito yokhazikika, yotsika mtengo yoyesa, yolimbana ndi kusokoneza, liwiro loyesa mwachangu, ndikuwongolera magwiridwe antchito a ntchito yoyesa madzi.
