Removal of Toxic Pb(II) Ions from Aqueous Solution by Nano Sized Flamboyant Pod (Delonix regia)
The removing of toxic heavy metals from aqueous solution by agricultural biosorbents was investigated by studying the effect of nano sized (Delonix regia) and chemically modified biosorbent citric acid Delonix regia (CADR) for removing of Pb2+ ions. TEM, XRD and EDS, FT-IR, SEM methods were used for characterizing the biosorbent(Delonix regia). The effect of contact time, pH,temperature, dosage of biosorbent, ... إقراء المزيد

A Study of Degradation Phenomena of the Stained Glass in some Cairo Palaces from 1850 to 1950
ABSTRACT _Egypt’s palaces have various openings and architectures, the most significant of which were those openings containing stained glass. Due to the degradation of most stained-glass windows in the Egyptian palaces that are full of artistic works of high production quality and the increase of degradation factors, whether natural or artificial, they should be immediate conserved to keep this heritage ... إقراء المزيد

Correlation between seminal lead and cadmium and seminal parameters in idiopathic oligoasthenozoospermic males
The exact causes of the decline in semen quality are not yet known, environmental factors have been considered to play an important role. Lead (Pb) and Cadmium (Cd) are two of the well-known reproductive toxicants to which humans are exposed occupationally and environmentally and can lead to negative effects on the testicular functions. The aim of this study was to ... إقراء المزيد

Estimation of lead and cadmium levels in flesh of some imported salted canned fish
Fish accumulates substantial amounts of metals in their tissues especially muscles and thus, consider one of major dietary sources of these metals for humans. The objective of the present study is to determine the concentration of lead and cadmium levels in flesh of some imported salted canned fish (Sardine, Salmon and Anchovies) by Atomic Absorption Spectrophotometer with Graphite furnace. Fourty ... إقراء المزيد
