Daim ntawv thov ntawm activated alumina li adsorbent
Cov khoom no yog siv rau kev rov tsim dua tshiab ntawm cov khoom degradation ntawm kev ua haujlwm hauv kev tsim cov hydrogen peroxide los ntawm cov txheej txheem anthraquinone.Nws yog cov khoom siv tshuaj tseem ceeb rau kev tsim cov hydrogen peroxide.Nws muaj cov hmoov av tsawg dua, tsis muaj kev puas tsuaj, thaj chaw loj tshwj xeeb thiab muaj peev xwm rov tsim dua tshiab, thiab lub neej ua haujlwm ntev.
Cov yam ntxwv cuam tshuam rau kev ua haujlwm adsorption
1.Particle loj: Qhov me me ntawm qhov loj me, qhov siab dua qhov muaj peev xwm adsorption, tab sis qhov me me ntawm cov particle loj, qhov qis dua particle zog, uas cuam tshuam rau nws lub neej kev pab cuam.
2. Tus nqi pH dej nyoos: Thaum tus nqi pH siab dua 5, qhov qis pH tus nqi, qhov siab dua qhov muaj peev xwm adsorption ntawm activated alumina.
3.Initial fluorine concentration nyob rau hauv cov dej nyoos: qhov siab dua qhov pib fluorine concentration, qhov loj dua lub peev xwm adsorption.
4. Lub alkalinity ntawm cov dej nyoos: qhov siab ntawm bicarbonate nyob rau hauv cov dej nyoos yuav txo tau lub peev xwm adsorption.
5.Chloride ion thiab sulfate ion.
6.Kev cuam tshuam ntawm arsenic: activated alumina muaj cov nyhuv adsorption ntawm arsenic hauv dej.Kev sib sau ntawm arsenic ntawm activated alumina ua rau txo qis ntawm qhov muaj peev xwm adsorption ntawm fluoride ions, thiab ua rau nws nyuaj rau elute arsenic ions thaum rov tsim dua.
