Abstract:
... Biopolymer made from bacteria is still not attractive compared to conventional commercial polymer because of the high cost of the substrate. The cyanobacterium Arthrospira platensis accumulates polyhydroxybutyrate (PHB) by using photosynthesis, making the production more promising compared to non-photosynthetic bacteria. However, this is still impractical for large-scale application. To increase P ...

Abstract:
... Selective filtration of dyes and inorganic salts is a challenge for the treatment of textile wastewater containing high salt contents. In this study, selective separation performance of PI/SiO₂ nanofiltration (NF) membrane for dye/inorganic salt mixtures was substantially improved through directional modulation of its thermal treatment parameters after phase inversion. After thermal modification, ...

Abstract:
... The current investigation focuses on a systematic study of application of two dried algal biomass (i.e., Nostoc sp. and Turbinaria vulgaris) in removal of Cr(VI) from synthetic solution as well as tannery industrial wastewater. The optimized conditions for Cr(VI) removal are nearly same for the both the biosorbents (i.e., pH 2.8, initial Cr(VI) concentration 100 mg L⁻¹, biomass dosage of 1.2g L⁻¹, ...

Abstract:
... Textile industries are among the ecologically unsustainable industries that release voluminous wastewater threatening ecosystem health. The constructed wetlands (CWs) are low-cost eco-technological interventions for the management of industrial wastewaters. The CWs are self-sustaining remediation systems that do not require an external source of energy and encompass simple operational mechanisms i ...

Abstract:
... A series of crosslinked poly(ionic liquid)s (C-PILs), with five different counter anions, were synthesised and investigated for their Cr(VI) binding properties. C-PIL with chloride as the counter anion (C-PIL-Cl) showed the highest sorption capacity (2.96 ± 0.03 mmol/g), while bis(trifluoromethanesulfonyl)imide led to minimum uptake. The chromium binding properties of C-PIL-Cl were investigated in ...
