cadmium (cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. the objective of this research was to compare cd adsorption behavior in six calcareous and four acid soils. soil samples were equilibrated with 0.01 m ca(no3)2 containing 25 to 3200 mg cd l−1. results showed that the tendency for adsorption was high at low cd concentrations (0-400...

the impact of de-oiled and dried two-phase olive mill waste (dw) amendment on the sorption,degradation, leaching, and persistence of the herbicide terbuthylazine in a mediterranean agricultural soil were studied under laboratory and long-term field conditions. the results are compared with those of a previous study, where the intermediary by-product of the olive-oil processing technology (ow) w...

The protocols selected and developed by the NIIIP Consortium have been validated in three end-of-cycle demonstrations. In each cycle, a team with expertise in technical product data, object modeling, workflow management, security, and knowledge representation came together and demonstrated how technical barriers to the dynamic creation, operation and dissolution of “virtual enterprises” are ove...

The cDNA corresponding to 137 bp of the 5’ untranslated region, the signal peptide, and the AI , A3, C1, and C2 domains of porcine factor Vlll (NIII) have been cloned and sequenced. Along with previously determined sequences of the porcine Nlll B domain and the A2 domain, this completes the sequence determination of the cDNA corresponding to the translated protein. Alignments of the derived ami...

recently, the use of biological absorbent in removal of hazardous pollutants such as heavy metals has increased because of the decrease in sludge problems, economical issues, high efficiency and compatibility with the environment. this study was done over the biosorption of nickel by biosolids obtained from the municipal wastewater treatment in a batch reactor. the pretreatment of the biosolids...

fine particles silicoaluminophosphate-34 were synthesized by hydrothermal sol-gel method. the effect of crystallization time, as one of the important synthesis factors on particle size and crystallinity, kinetic and equilibrium adsorption, and selectivity of co2 / ch4 has been studied in this work. the adsorption isotherms are obtained at moderate gauge pressures (100-3000 kpa) and temperatures...
