The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

introduction: a major concern of human being is accumulation and toxicity of heavy metals in their body. copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. different treatment methods have been proposed for removing metals from contaminated water by researchers. among these methods, sorption seems a better method with high removal efficiency. in this s...

The accumulation of rare-earth and heavy metal ions from wastewater is important for industrial technology. However, practical accumulators are expensive with respect procurement raw materials, synthesis, preparation. Therefore, it preferable to accumulate using sustainable resources, such as natural polymers. Fucoidan, a water-soluble polymer, sulfated polysaccharide the cell-wall brown algae....

In the field of plant nutrition there are many problems which require, for their solution, an understanding of the distribution of accumulated mineral salts between various plant parts. In their discussion of interrelations of salt accumulation with growth and development of the plant body, Steward and Sutcliffe (14) have provided a background for understanding distribution problems. But, they ...

Abstract Water system closure in recycled containerboard mills may have reached a technical limit due to the accumulation of organic and inorganic contaminants process water. The specific water chemistry characteristics with restricted systems were analyzed computer model was developed simulate calcium carbonate solubility presence volatile fatty acids under relevant mill conditions. A strong l...

The ionophoretic antibiotics, monensin and lasalocid, bind numerous mono- and divalent cations, primarily in dimeric complexes that facilitate the passage of metal ions through hydrophobic lipid membranes. Ionophores vary in their affinity for metal ions. Similarly, transport rates of the resulting complexes depend in part upon the affinity constant of the drug ion-binding interaction, and in p...
