These stones consist of three different varieties; white, green and yellow. As it is known, in recent years, the use of low-cost and easy-to-supply natural raw materials as adsorbents for removing various pollutants from wastewaters has become a very important issue. In this context, the adsorbent characteristic of green Bayburt stone was investigated by using a Taguchi experiment design which is one of the statistical experimental design methods after milling to very small dimensions (d50=13.20 µm). In the experimental studies cobalt (Co) element was selected as a model heavy metal. The optimum adsorption parameter values of green Bayburt stone were determined as 7 for pH, 250 mg/L for initial metal concentration and 0,250 g for adsorbent dose. According to the findings, adsorption capacity of the adsorbent for Co(II) was calculated as qe = 60.16 (mg/g), and this value was found to be comparable with many studies in the literature.</dc:description><dc:date>2019</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/15102</dc:identifier><dc:identifier>https://doi.org/10.28948/ngumuh.517139</dc:identifier><dc:language>tr</dc:language><dc:relation>Niğde Ömer Halisdemir Üniversitesi Mühendislik Bilimleri Dergisi</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/15102</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
