Influencing yam ntawm activated alumina
Jan 07, 2022
(1) Particle loj: qhov me me particle loj, siab dua lub peev xwm adsorption, tab sis qhov me me particle loj, qhov qis particle zog, uas cuam tshuam rau nws lub neej kev pab cuam.
(2) pH tus nqi ntawm cov dej nyoos: thaum pH tus nqi ntau dua 5, qhov qis pH tus nqi, qhov siab dua qhov muaj peev xwm adsorption ntawm activated alumina.
(3) Thawj fluorine concentration nyob rau hauv cov dej nyoos: qhov siab dua qhov pib fluorine concentration, qhov loj dua lub peev xwm adsorption.
(4) Raw dej alkalinity: Lub siab concentration ntawm bicarbonate nyob rau hauv cov dej nyoos yuav txo tau lub peev xwm adsorption.
(5) chloride thiab sulfate ions.
(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 hauv qhov muaj peev xwm adsorption ntawm fluoride ions, thiab nws nyuaj rau elute arsenic ions thaum rov tsim dua.
