Abstract: Seed coat of Jatropha curcas was investigated for the removal of some selected metals from aqueous solutions. The selected metal ions are Cu, Ni and Cr. In this work, impact of pH of solution and sorption time on sorption capacity was investigated. At a pH of 5.0, 6.0 and 5.0 relatively to sorption time of 120mins, 60mins and 120mins respectively, 88.88%, 99.78% and 97.81% of Ni, Cu, and Cr were removed accordingly. Adsorption data analyzed using Langmuir and Freundlich models shows that Cu and Cr however followed Langmuir isotherms and not Freundlich while Ni adsorption conforms to both Langmuir and Freundlich models. This study shows that prepared biomass of Jatropha curcas husk can be used as an adsorbent for removal of Cu, Ni and Cr from wastewater or any industrial effluent.

Abstract: Twenty Reflection seismic sections have been used to shed light on the subsurface structural setting and the hydrocarbons entrapment styles in the Razzak field of the Egyptian Western Desert. This is achieved through integrated geological and geophysical studies utilizing a number of maps and cross sections. The interpretation has been traced four reflectors, the Massajid Formation, Alamein Dolomite Member, Abu Roash "G" Member, and the Apollonia Formation.The NW-SE and NE-SW trending seismic sections revealed a number of Late Cretaceous wrench and shear faults forming horsts allover the mapped field. These faults led to a very thin Lower Cretaceous section occupies the horst block area compared to very thick section on the downthrown side of the two main faults. For some instances dry hole conditions occur due to missing of an adequate structural closure on the horst block area.The TWT maps on the top of the traced reflectors reveal different structural closures with lateral strike-slip fault displacement. These maps revealed that the field almost tectonically ceased since the Late Cretaceous time with minor NE faulting accompanied with tilting tectonisms.
