The process of olive oil extraction produces olive stone, a residue which cause considerable problems of disposal. This paper proposes and analyzes an original use of olive stone in order to improve the heat insulation performances of cement lime mortar and reduce its final density. To this purpose, the paper illustrates a set of small-scale tests, which were conducted on specimens of cement li...

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...

in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

What is an olive? Well, botanically speaking, the fruit of the olive tree is a drupe, or stone fruit, and is cultivated on all continents (Figure 1), but the olive is much more than a fruit — it’s a symbol. Olives and the trees that bear them are mentioned in The Odyssey, the Quran, the Torah, and the Bible, just to name a few. Representing peace, abundance, and victory, this divine fruit has i...

the performance of olive stone activated carbon (osac) for sorption of cu2+, zn2+ and ni2+ ions was investigated via batch technique. osac materials were prepared under different physially activation conditions. olive stone waste was physically activated with n2 gas and steam gas at 900oc at 3.5h hold time (osac-3) was choice as the best one for cu2+, zn2+ and ni2+ removal. characterization for...

Olive fruits contain an n-alkane series of saturated hydrocarbons mainly in the pulp. Lower amounts of a complex mixture of paraffins, unresolved by gas chromatography (UCM--unresolved complex mixture), have been found in cuticle, stone (woody shell and seed), olive leaves, and talc used as an aid to olive oil extraction. The amounts of both kinds of hydrocarbons are related to the olive cultiv...

The purpose of this study was to characterize olive core collection with amplified fragment length polymorphism (AFLP) markers and fruit traits and to determine AFLP markers significantly associated with these fruit characters in olive. A total of 168 polymorphic AFLP markers generated by five primer combinations and nine fruit traits were used to characterize relationships between 18 olive cul...

The use of biomasses that result from the agriculture and food industries in removing heavy metals from wastewaters is attracting increasing interest. We present a joined potentiometric and cross polarization magic angle spinning (CP-MAS) carbon-13 (13C) nuclear magnetic resonance (NMR) study on the interaction of olive stones with copper(II), nickel(II), and cadmium(II). The potentiometric mea...
