abstract background and purpose:the main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes. materials and methods:the present study was conducted in bench-scale. the spectrophotometer dr 5000 was used to determine th...

The release of Indigo Carmine in waterbodies may cause serious impact aquatic ecosystems and human health. There is an interest developing green, low-cost effective adsorbents for the removal toxic dyes from textile effluents. This study proposed adsorbent material at nanoscale using waste Moringa oleifera seeds generated after oil extraction. were grounded to obtain nanoscale. Batch-adsorption...

Received 04 October 2012, Revised 15 December 2012, Accepted 16 December 2012 -------------------------------------------------------------------------------------------------------------------------------------------Abstract The present work demonstrates the comparative extraction efficiency of p-tert-butylcalix[4]arene (1) and its derivatives (2-4) toward a series of some selected reactive dy...

A DNA extraction system was designed and fabricated using an AOM (aluminum oxide membrane) with 200 nm pores and PDMS microfluidic channels. The membrane was patterned using soft lithography techniques and SU-8 photolithography on the membrane. After making the pattern with SU-8, the AOM was observed using an SEM (scanning electro microscope) to verify the AOM structure was not damaged. From th...

The aim of this study was to compare the efficiency of DNA extraction from water as well as from blood samples spiked with A. fumigatus spores, using selected commercial kits. Extraction of DNA according to manufacturer's protocols was preceded by blood cells lysis and disruption of fungal cells by enzymatic digestion or bead beating. The efficiency of DNA extraction was measured by PCR using A...
