Removal of cadmium from aqueous solutions using clinoptilolite: Influence of pretreatment and regeneration
Gedik, Kadir; İmamoğlu, İpek (2008-06-30)
In this study, Cd removal from aqueous solutions via clinoptilolite was investigated in terms of the effect of pretreatment and regeneration. Four different chemicals (NaCl, KCl, CaCl2 and HCl) were tested for this purpose. Samples treated by a total of 20 bed volume (BV) of 1 M NaCl solution prepared in tap water with no pH adjustment were found to perform satisfactorily. Five exhaustion and regeneration cycles were then carried out, revealing an increasing Cd removal capacity, coupled with constant Cd elu...
Removal of methylene blue by new tunable aryl/alkyl ionic liquids/salts (TAAILs) from aqueous solution
Özdemir, Melek (Informa UK Limited, 2019-10-16)
The removal of methylene blue (MB) from aqueous solution has been investigated using new tunable 1-aryl-2-alkyl-3,5-dimethylpyrazolium hexafluorophosphate salts ([Ph(R)C(R?)pz][PF6], R: -Cl, -Br, -Me, -OMe, R?: -C2H5, or -C4H9) as an extractant and methylene chloride as a diluent. The influence of p-substituent and alkyl chain length on the removal efficiency of MB from aqueous solution was investigated. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up...
Removal of Ni(II) Ions From Aqueous Solutions Using Activated-Carbon Prepared From Olive Stone by ZnCl2 Activation
The aim of this study is to remove Ni (II) ions from aqueous solutions by adsorption. Activated-carbon prepared from olive stone (ACOS) was used as adsorbent. Different particle size and concentration of ZnCl2 were studied to optimize adsorbent surface area. Initial concentration, temperature, time, and pH were selected as parameters. According to the experiments results, the equilibrium time, optimum pH, and adsorbent dosage were found 60 min, pH > 6, and 1.0 g/50 mL, respectively. In addition, raw olive s...
Removal of boron from aqueous solutions by continuous polymer-enhanced ultrafiltration with polyvinyl alcohol
Dilek, C; Ozbelge, HO; Bicak, N; Yılmaz, Levent (2002-01-01)
Boron is a highly contaminating metal due to its toxic effects for plants even at very low concentrations. Continuous polymer-enhanced ultrafiltration (PEUF) was applied for removal of boron from aqueous solutions. The effects of operating parameters on the performance of PEUF were investigated. A commercial polymer, polyvinyl alcohol (PVA) was used as the boron-complexing agent. The methodology consists of two steps: complexing boron with PVA following separation of boron and polymer complexes by ultrafilt...
