Fe(III)–chitosan microbeads (Fe–CTB) were prepared using a chemical coprecipitation method. SEM–EDX, FTIR, XRD, TGA, BET, and pH pzc performed for the characterization of adsorbent. Various parameters optimized as pH, adsorption time, adsorbent dose, initial Cr(VI), PO43− ion concentration effect assorted ions studies. Fe–CTB revealed more than 80% detoxification 100 mg L−1 at 3 with 60 min sti...

Fourier transform infrared (FTIR) imaging is a powerful tool for the assessment of bone quality; however, it requires the preparation of thin bone sections. Conventional poly(methyl methacrylate) (PMMA) embedding for the preparation of sections takes more than two weeks and causes denaturation of the bone. Development of a quick and easy sample preparation technique without denaturation is need...

This study was aimed to determine the spatial variation in anthropogenic pressure exerted on surface water in the Podhale region (southern Poland), which is one of the most popular tourist destinations in Poland. The assessment was based on the dynamics and relationships between microbiological and chemical indicators of water quality throughout the major rivers of this region-Dunajec, Czarny D...

The reverse osmosis (RO) brine generated from the Al-Quds University wastewater treatment plant was treated using an epuvalisation system. The advanced integrated wastewater treatment plant included an activated sludge unit, two consecutive ultrafiltration (UF) membrane filters (20 kD and 100 kD cutoffs) followed by an activated carbon filter and a reverse osmosis membrane. The epuvalisation sy...

A pyrrhotite and sulfur-circulating packed bed reactor (PS-CPBR) was constructed to study the removal process mechanism of NO3−-N PO43−-P with different electron donors. The results showed that performance mixed donors (pyrrhotite sulfur) superior single donor (pyrrhotite). optimum conditions in PS-CPBR were a hydraulic retention time (HRT) 12 h C/N 0, average efficiency 100% 86.39%. sulfur abl...
