Solvent recovery from photolithography wastes using cellulose ultrafiltration membranes
Savaş, Aygen; Çulfaz Emecen, Pınar Zeynep (2022-04-05)
Solvent recycling and reuse are indispensable for ensuring a sustainable chemical industry and circular economy. In this study we report the fabrication of cellulose ultrafiltration membranes and their application in recovery of propylene glycol methyl ether acetate (PGMEA) used as developer solvent in SU-8 photolithography. Cellulose membranes were fabricated via alkaline hydrolysis of cellulose acetate membranes in aqueous NaOH. Membrane permeance and molecular weight cut-off (MWCO) were tuned via changin...
Solvent recovery from photolithography waste using cellulose ultrafiltration membranes
Savaş Alkan, Aygen; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2021-8)
Cellulose flat sheet ultrafiltration membranes were fabricated for the investigation of their separation performance in Organic Solvent Ultrafiltration (OSU) applications and for the solvent recovery from photolithography wastes. Firstly, cellulose acetate membranes were produced and then, these were converted into cellulose membranes via alkaline hydrolysis. The membranes were cast from polymer solutions containing cellulose acetate as polymer with 20-30% concentration range, dimethyl sulfoxide (DMSO) as s...
Solvent Compatibility of Parylene C Film Layer
Koydemir, H. Ceylan; Külah, Haluk; Özgen, Canan (2014-04-01)
Parylene C has been preferred in various microfluidic and packaging applications as a chemical barrier; therefore, its durability in chemicals is critical to maintain functionality of the devices. In this paper, we investigated solvent compatibility of Parylene C in a range of solvents with regard to swelling of it and the change in its surface roughness at room temperature. The results of Parylene C swelling were associated with solubility parameter, delta (cal/cm(3))(1/2), which is predicted from the para...

Solvent extraction behaviour of scandium from lateritic nickel-cobalt ores using different organic reagents
Ferizoglu, Ece; Kaya, Serap; Topkaya, Yavuz Ali (2018-04-01)
Scandium is one of the most important and strategic metals that can be recovered as a by-product from lateritic nickel-cobalt ores. In this research, different extractants were investigated to extract scandium from sulphate medium by using solvent extraction method. Generally, the organic extractants are classified as acidic, neutral and basic reagents. Thus, the aim of the present study was to compare scandium extraction efficiencies of some acidic, neutral and basic organic reagents. For this reason, Ionq...
