Due to growing production, carbon nanotubes (CNT) may soon be found in a broad range of products and thus the environment. In this work, an algal growth test was developed determine effects pristine oxidized CNT on green algae Chlorella vulgaris Pseudokirchneriella subcapitata. suspensions were prepared medium characterized taking into account suspension age, reduced light transmittance nanoparticle defined as shading quantified by UV/vis spectroscopy, agglomeration cells. Growth inhibition...
This study investigated the toxicity of double walled carbon nanotubes (DWCNTs) to three aquatic organisms, namely, Pseudokirchneriella subcapitata , Daphnia pulex and Poecilia reticulata under influence exposure media properties specifically ionic strength organic matter represented by humic acid. Results indicated that enhanced DWCNTs agglomeration whilst acid stabilized CNTs in turn inhibited formation aggregates. LC 50 s for D. were higher at 2.81 4.45 mg/L pristine oxidised DWCNTs,...
Silver impregnated carbon nanotubes and cyclodextrin polymers were synthesised by first functionalising in a mixture of nitric sulphuric acid before impregnating them with silver nanoparticles. The functionalised then polymerised β using hexamethylene diisocyanate as the linker. characterised various techniques. tested for their ability to destroy bacteria water found reduce bacterial cell counts spiked E. coli (ATCC 25925) low zero cfu/mℓ. Furthermore, could absorb 58% para-nitrophenol...
Increasing demand for safe drinking water and the problems associated with some existing treatment methods have made it vital development of new technologies to address these challenges. This study explores use nanosized silver copper impregnated on polyurethanes possible in disinfection. It also investigates adsorption organics by metal water. Copper nanoparticles were immobilized carbon nanotube embedded water-insoluble cyclodextrin polyurethane polymers. The characterized various...
