“…When pH>7, the precise mechanisms involved in the adsorption performance of MOF Cu-BTC is complex and still need to be studied. For example, the H-bonding interaction between oxygencontaining functional group of MOF Cu-BTC and -NH 2 group of CR [27], and other mechanisms like π-π interaction between the highly delocalized π electrons in CR dye and 1,3,5-benzenetricarboxylic acid molecules both might contribute to the adsorption of CR from aqueous solution [28].…”

“…SiO 4 tetrahedral kısım negatif olup, Al 3+ tetrahedral yapının merkezindeki Si 4+ ile yerdeğiştirdiğinde gözeneklerde depolanmış zayıf katyon yapıyı negatif olarak yükler ve negatif yük katyonlar tarafından dengelenir [9,[12][13][14][15]. Kuvvetli asitlikleri (Bronsted (Si-OH-Al) ve Lewis (kafesteki katyonlar) asidik merkezler), homojen gözenek boyutu, seçicilik ve kararlılık gibi özelliklerinden dolayı son yıllarda ağır metal iyonları, fenoller ve boyar madde gibi kirleticilerin eser miktarlarını uzaklaştırmak amacıyla kullanılmaktadırlar [8][9][10]16]. Klinoptilolit dünyada ve Türkiye'de rezerv olarak en bol bulunan doğal zeolit minerallerinden biridir.…”
