    Abstract: The electrokinetic of chromium, copper, silver and gold ions removal from synthetic and wastewater via electro-flotation was investigated. Kinetics and thermodynamic parameters of the electro-flotation process were determined. The effect of initial pH and metal ion concentration, treatment time and temperature showed that the maximum removal was ac... Show More

    Abstract: Quaternized PDMAEMA (qPDMAEMA) was used to prepare nanofibers by electrospinning. At first the DMAEMA monomer was quaternized using Hexyl, dodecyl and hexadecyl bromide. Then the quaternized DMAEMA was polymerized by free radical polymerization. This polymer was characterized by 1HNMR, GPC, and thermal analysis (DSC and TGA). The (qPDMAEMA) was ble... Show More
