Article Citation - WoS: 17Citation - Scopus: 16Synthesis, Characterization and Adsorption Studies of Phosphorylated Cellulose for the Recovery of Lithium From Aqueous Solutions(Editura Acad Romane, 2021) Recepoğlu, Yaşar Kemal; Yüksel, AslıIn this study, pristine cellulose was functionalized by the phosphorylation reaction to make it suitable for lithium separation. After characterization studies of the synthesized adsorbent with SEM, EDX, FTIR, TGA and XPS, the effects of various parameters on the lithium uptake capacity of the adsorbent were examined. The analysis of equilibrium data by several adsorption models showed that maximum adsorption capacity of the adsorbent was found to be 9.60 mg/g at 25 degrees C by the Langmuir model. As initial concentration and contact time increased, adsorption capacity also increased, however, mild temperature (25-35 degrees C) and pH (5-6) were better for the adsorption of lithium. 80% of lithium adsorption within three minutes proved the fast kinetic nature of the adsorbent. A 99.5% desorption efficiency of lithium was achieved with 0.5 M H2SO4, among HCl and NaCl with different molarities. Phosphorylated cellulose was shown to be a favorable adsorbent for the recovery of lithium from aqueous solutions.Conference Object Citation - Scopus: 1Enterprise Systems Applications Development Plans To Build and Develop Robust and Environmentally Sensitive Green Logistics Systems Management Software(Springer Verlag, 2009) Yıldız, Türkay; Yercan, FundaWithin the concept of enterprise-wide development of environmentally sensitive systems' application modules to fully integrate all-in-one green logistics services principles have received much attention and consideration from practitioners, academia, and from the industry, for about more than a decade. However, by taking into the consideration of the multidisciplinary nature of the issue, large scale effective collaborative framework is needed to be developed. Therefore, utilization of UML diagrams, class definitions, defining class relationships, fields, tables, views, etc. so on play crucial roles in the design phases of the enterprise system. Thus, this article largely deals with the major logistics work processes and their interactions within the consideration of environmental engineering issues on business operations to address step-by-step process control mechanisms to provide necessary input to build robust-design and better implementation of the needed IT software backbone.
