Desalinasyon ve bor giderimi için membran teknolojilerine son yıllarda ilgi duyulmaktadır. Günümüzde membran bazlı ayırma prosesleri, çevre dostu olmaları ve enerji/maliyet tüketimindeki verimlilikleri nedeniyle tercih edilmektedirler. Bu yeni teknolojilerden biri de membran distilasyondur. Henüz akademik seviyede olan araştırmalar sonucunda membran distilasyon gibi ileri teknoloji ile %99,99 üzeri saflaştırma ve giderim yapmak mümkündür. Bu çalışmada, biyobozunur polimerlerden olan saf ve grafen katkılı polilaktik asit (PLA) membranlar üretilerek membran distilasyon tekniği ile sulardan bor giderimi yapılmıştır. Sıcaklığın, bor konsantrasyonunun, grafen oranının bor reddi ve su akısı değerlerine etkisi belirlenmiştir. Sonuç olarak tüm sıcaklıklarda ve tüm grafen katkılı PLA membranlarla %99 üzeri bor retleri elde edilmiştir. Özellikle grafen katkısıyla akı değerleri 13 kg/m2.h olarak elde edilmiştir.

Boron removal by vacuum membrane distillation with graphene doped polylactic acid membrane

Öz

Membrane technologies for desalination and boron removal have attracted interest in recent years. Today, membrane-based separation processes are preferred due to their environmental friendliness and efficiency in energy/cost consumption. One of these new technologies is membrane distillation. As a result of researches that are still at academic level, it is possible to purify and remove over 99.99% with advanced technology such as membrane distillation. In this study, pure and graphene-doped polylactic acid (PLA) membranes, which are biodegradable polymers, were produced and boron was removed from water by membrane distillation technique. The effects of temperature, boron concentration, graphene ratio on boron rejection and water flux values were determined. As a result, boron rejections above 99% were obtained at all temperatures and with all graphene-doped PLA membranes. The flux values were obtained as 13 kg/m2.h, especially with the graphene additive.
