Fiziksel ve kimyasal olarak modifiye edilmiş proses atığının sentetik atıksudan ağır metal gideriminde başarısının araştırılması

Öz

Bu çalışmanın amacı, bor zenginleştirme tesisi çıkışından alınan posa atığının (BZA) ses ve asit ile laboratuar ortamında modifiye edilerek (MBZA) nikel (Ni⁺²) ağır metalinin adsorpsiyon sisteminde giderimine verimi araştırılmıştır. Deneysel araştırma kesikli sistemle, farklı adsorban dozları (0,1-5 g/100 mL), farklı pH (2-10), farklı temas süresi (0-150 dakika) ve farklı karıştırma hızlarında (100, 200, 300, 400 rpm) gerçekleştirilmiştir. MBZA ait kimyasal özellikler ve SEM görüntüleri belirlenmiştir. MBZA'nın nikel adsosorpsiyonu sırasında elde edilen korelasyon katsayılarına göre Langmuir modeline daha uyumlu bulunmuştur. Kinetik veriler arıtım sonucunda elde edilmiş olup MBZA için elde edilmiş olan qmax değeri 16.01 mg/g’dir.

Investigation of the success of physical and chemically modified process waste in heavy metal removal from synthetic wastewater

Öz

This study investigated removal efficiency of nickel in adsorption system by using the process waste obtained from the exit point of boron enrichment plant, modified with sound and acid in laboratory. The experimental study was conducted in an intermittent process by taking into account the criteria of different adsorbent dosages (0,1-5 g/100 mL), pH (2-10), contact times (0-150 minutes) and mixing speeds  (100, 200,300, 400 rpm). Chemical properties and SEM images pertaining to modified boron enrichment waste (MBZA) were specified. In nickel removal, it was observed that the obtained results were found more concordant with Langmuir Isotherm models as evidenced by correlation coefficients. Kinetics data were obtained from treatment results, and qmax value obtained for MBZA were found as 16,01 mg/g.
