摘      要：Tight ceramic ultrafiltration membranes have been proven to exhibit good rejection performance for reactive dye wastewater at high temperatures because of their high thermal and chemical ***,the application of ceramic membranes for the treatment of cationic dye wastewater is challenging because of their surface *** this study,a ceramic membrane is modified by grafting aminosilane(KH-551)to enhance the positive charge of the membrane *** rejection performance of the charged modified ceramic membrane toward the methylene blue solution is significantly *** modification substance is bonded to the ceramic membrane surface via covalent bonding,which imparts good thermal *** modified ceramic membrane exhibits stable separation performance toward the methylene blue ***,this study provides valuable guidance for the adjustment of the ceramic membrane surface charge for treating industrial cationic dye wastewater.
