Four lignocellulosic materials (walnut shell, chestnut pine wood and burnt wood) were analyzed as biosorbents to remove nickel ions in aqueous solution. The optimal pH condition was determined. Due this, a range of different pHs (3.0 7.5) tested. adsorption isotherms kinetics established. To plot Langmuir Freundlich isotherms, batch tests made with variable concentrations (5 200 mg L−1). pseudo...

walnuts are one of the most important nut crops worldwide. the area under cultivation increases every year. in 2008, the food and agriculture organization reported exports of about $17.1 billion. the country of iran is the 4th largest producer of walnuts in the world. stages from production to consumption are very important, because the condition and quality of the shelled nutmeats affects the ...

Introduction: Lipid oxidation, including LDL oxidation, plays a pivotal role in development of atherosclerosis. Supplementing diet with antioxidants, such as vitamin E and walnut husk hydroalcoholic extract, may prevent LDL oxidation. In the present study, we investigated the in vitro effects of walnut husk hydroalcoholic extract on serum LDL oxidation caused by copper sulfate. Method: Blood sa...

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

Nanocables with a single-wall carbon nanotube (SWCNT) core and a ZnS shell were directly synthesized in one step through a thermal reaction method by using carbon, Zn, and FeS powder as starting materials. The as-fabricated nanocables were studied using scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The nanocables have diameters of ~50 nm, lengths of sev...

The objective of the present study was to examine some physical and chemical shell kernel attributes promising walnut types selected from Bingol province in Turkey. possesses a rich population almost all which are seedling-grown. Shell cracking resistance, firmness, percentage, pellicle cotyledon color, total oil ratio, phenol content, antioxidant capacity as DPPH were analyzed evaluated. resis...

This rooting study was set up to compare Paradox walnut softwood cuttings from trees which had been: a) propagated through tissue culture, and b) from conventionally grown trees (seedlings). A number of studies on rooting of both hardwood and softwood cuttings of walnut trees have been made by various workers. Although it was reported by Lee, et. al. (1) and others that 100%rooting was obtained...

In the present study, a highly sensitive and simple high-performance liquid chromatographic method was developed and validated for simultaneous determination of three unsaturated fatty acids, αlinolenic acid, linoleic acid and oleic acid in walnut oil. Unsaturated fatty acids were quantified through HPLC using a reversephase C8 column and UV detector. Besides, the antioxidant activity of walnut...

Aspects of the susceptibility of English walnu~ to infection by Xanthomonas campestris pv. juglandis, the bacterium which causes walnut blight, were investigated. Leaves of 15 mature English walnut trees were inoculated with the bacterium which causes walnut blight, and after 35 days each cultivar was rated for infection severity. During the following dormant season, the buds associated with th...
