From its creation to its disposal, there are environmental and health problems associated with polyvinyl chloride (vinyl), the major component of vinyl flooring. The production of vinyl creates toxic waste that must be dumped or incinerated. Because very little vinyl is recycled, the waste material must also be landfilled or burned. Furthermore, the heavy chlorine content of these materials res...

rivastigmine hydrogen tartrate (rht), one of the potential cholinesterase inhibitors, has received great attention as a new drug candidate for the treatment of alzheimer's disease. however, the bioavailability of rht from the conventional pharmaceutical forms is low because of the presence of the blood brain barrier. the main aim of the present study was to prepare positively charged eudragit r...

Dissolved natural organic matter (DOM), particularly the low molecular weight DOM, can affect the performance of water treatment processes and serve as a main precursor of disinfection by-products (DBPs) during chlorination. In this study, electrospray ionization coupled to Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS) was used to characterize the low molecular wei...
