This paper presents the investigation of the ammonia-nitrogen and phosphates sorption from simulated reclaimed wastewater by modified clinoptilolite. The results showed that the modified clinoptilolite has a high sorption efficiency and removal performance. The ammonia-nitrogen and phosphates removal rate of the modified clinoptilolite reached to 98.46% and(More)
Stacked chitosan nanofibers with an average diameter of 75 nm were successfully produced by electrospinning using 5 wt% chitosan in acetic acid as the spinning solution. The fibers were then cross-linked with glutaraldehyde to remove chromium [Cr(VI)] from water via static adsorption. It was found that the adsorption correlated well with pseudo-second order(More)
Adenosine 5'-triphosphate (ATP) is a multifunctional molecule that participates in many important biological processes. Currently, fluorescence indicators for ATP with high performance are in demand. Reported herein is a novel water-soluble triarylboron compound which displays an apparent ATP-dependent fluorescence enhancement when dispersed in water. It(More)
A new nanogel indicator (NGI) for ratiometric fluorescent detection of intracellular pH values has been reported. In aqueous solution, the NGI can be used for ratiometric sensing of pH changes with a large hypsochromic shift of 100 nm in the green-red region and reversible. Furthermore, the NGI has been used to calibrate the cytosol pH value in living cells.
TiO2/cellulose nanocomposite was synthesized by in situ generation of titanium dioxide (TiO2) nanocrystals on cellulose fibers (CF) via facile hydrolysis of TiOSO4. Cellulose was intended as a scaffold to immobilize TiO2 nanoparticles (NPs), but turned out surprisingly to be also a chemical template that directed the crystal growth. As a result, spindle(More)
The pH of mitochondria (pHm) has a close relationship with many biological processes. Here we developed a new indicator Mito-pH-1 for the ratiometric fluorescence detection of the mitochondria pH value, which has excellent tolerance to environmental change. And Mito-pH-1 has been used for the first time to monitor the change of pHm under temperature and(More)
A laboratory scale up-flow anaerobic-aerobic biological filter was constructed to treat synthetic ore floatation wastewater. Volcanic stone was applied as packing media for aerobic section. Biodegradation of some common ore floatation reagents as potassium ethyl xanthate dithiophosphate and turpentine were evaluated. An average COD reduction rate of 88.7%(More)
