Removal of textile dye from aqueous solutions by nanofiltration process
The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...
متن کاملIdentification of highly concentrated dextrose solution (50% dextrose) extravasation and treatment--a clinical report.
Treatment for significant hypoglycemia includes administration of dextrose containing agents, including 50% dextrose (D50%W) intravenously. Significant extravasation of D50%W can lead to complications, including skin and soft tissue injury, loss of limb, or death. The aim of this case report, using an interdisciplinary team approach, explores extravasation protocols as well as literature review...
متن کاملProducing over 100 ml of highly concentrated hyperpolarized solution by means of dissolution DNP.
New low-temperature inserts compatible with an existing hyperpolarizer were developed to dynamically polarize nuclei in large samples. The performance of the system was tested on 8 ml glassy frozen solutions containing 13C-labeled molecules and doped with nitroxyl free radicals. The obtained 13C low-temperature polarization was comparable to the one measured on 20 times smaller sample volume wi...
متن کاملApplicability and costs of nanofiltration in combination with photocatalysis for the treatment of dye house effluents
Nanofiltration (NF) is a capable method for the separation of dyes, which can support and even improve the applicability of photocatalysis in effluent-treatment processes. The membrane process usually will need a special pre-treatment to avoid precipitation and fouling on the membrane surface. Conceptually NF can be applied in the pre-treatment prior to the catalytic reactor or in connection wi...
