“Sonsuz kimyasallar” olarak bilinen PFAS nedir?<\/b><\/p>\n

4.700’den fazla kimyasal maddeden olu\u015fan perflorlu ve poliflorlu alkil maddeler (PFAS),\u00a0insanlarda ve \u00e7evrede zamanla biriken, yayg\u0131n olarak kullan\u0131lan, insan yap\u0131m\u0131 kimyasallar grubu<\/strong>. Bu kimyasallar, \u00e7evremizde ve v\u00fccudumuzda son derece kal\u0131c\u0131 olduklar\u0131 i\u00e7in ‘ sonsuz kimyasallar ‘ olarak biliniyor. Rice University’de g\u00f6rev yapan bir ara\u015ft\u0131rma ekibi ise, PFAS filtreleme s\u00fcrecini k\u00f6kten de\u011fi\u015ftirebilecek yeni bir malzeme geli\u015ftirdi.<\/p>\n

Bak\u0131r ve al\u00fcminyum temelli katmanl\u0131 \u00e7ift hidroksit (LDH) yap\u0131s\u0131na sahip bu filtre, uzun zincirli PFAS bile\u015fiklerini mevcut sistemlere g\u00f6re yakla\u015f\u0131k 100 kat daha h\u0131zl\u0131 absorbe<\/strong> edebiliyor. \u00dcstelik yaln\u0131zca yakalamakla kalm\u0131yor, bu maddelerin b\u00fcy\u00fck b\u00f6l\u00fcm\u00fcn\u00fc par\u00e7alayarak yok etmeye de yard\u0131mc\u0131 oluyor.<\/p>\n

Bak\u0131r-al\u00fcminyum,\u00a0100 kat daha h\u0131zl\u0131 filtre<\/b><\/p>\n

Kar\u015f\u0131la\u015ft\u0131rmak ad\u0131na, mevcut filtreleme \u00e7\u00f6z\u00fcmleri PFAS’\u0131 sudan ay\u0131rabiliyor, ancak bu kimyasallar daha sonra \u00f6zel tesislerde depolanmak zorunda kal\u0131yor. Tam imha i\u00e7in ise son derece y\u00fcksek s\u0131cakl\u0131klar<\/strong> gerektiren, maliyetli ve karma\u015f\u0131k termal i\u015flemler uygulan\u0131yor. End\u00fcstriyel \u00f6l\u00e7ekte PFAS’\u0131 tamamen ortadan kald\u0131rabilen bir sistem ise hen\u00fcz yayg\u0131n kullan\u0131mda de\u011fil.<\/p>\n

<\/span> Rice ekibinin geli\u015ftirdi\u011fi LDH malzemesi, al\u00fcminyum atomlar\u0131n\u0131n bir k\u0131sm\u0131n\u0131n bak\u0131rla de\u011fi\u015ftirilmesiyle<\/strong> olu\u015fturuluyor. Pozitif y\u00fckl\u00fc bu yap\u0131, negatif y\u00fckl\u00fc PFAS zincirleriyle daha kolay ba\u011f kurabiliyor. Bu sayede filtreleme h\u0131z\u0131 ciddi \u00f6l\u00e7\u00fcde artarken, i\u015flem verimlili\u011fi de y\u00fckseliyor. <\/figure>\n

Ara\u015ft\u0131rmac\u0131lara g\u00f6re PFAS’\u0131 “yok edilemez” k\u0131lan karbon-flor ba\u011flar\u0131, 400\u2013500\u00b0C gibi g\u00f6rece d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda k\u0131r\u0131labiliyor. Bu s\u00fcre\u00e7te a\u00e7\u0131\u011fa \u00e7\u0131kan flor, LDH i\u00e7inde tutuluyor ve kalsiyumla ba\u011flanarak kalsiyum flor\u00fcr formuna d\u00f6n\u00fc\u015f\u00fcyor. Ortaya \u00e7\u0131kan bu bile\u015fik, standart depolama alanlar\u0131nda g\u00fcvenli \u015fekilde bertaraf edilebiliyor. Hen\u00fcz erken a\u015famada olsa da bu teknoloji, PFAS kirlili\u011fiyle m\u00fccadelede hem daha h\u0131zl\u0131 hem de daha s\u00fcrd\u00fcr\u00fclebilir bir yol sunmas\u0131 a\u00e7\u0131s\u0131ndan \u00f6nemli bir d\u00f6n\u00fcm noktas\u0131 olabilir.<\/p>\n\n
