in this research, a cold model of internally circulating fluidized bed is investigated. the aim is to find the effects of some of the operating parameters on the performance of the reactor. experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). the bed was loaded with white silica particles (dp = 0.15 -...
The purification of wastewater is preferred using the adsorption by column due to process’s high efficiency. Column investigations are performed remove hazardous pollutants and demonstrate efficiency in treatment process. Cadmium zinc exist radioactive industrial wastes. Therefore, this work interested cadmium removal from utilising a fixed-bed column. Zirconia–silicate composite (ZrO2–SiO2) wa...
Adenosine deaminase (adenosine aminohydrolase EC 3.5.4.4) has been purified 468,000-fold from pooled human erythrocytes. The procedure developed was used to isolate the enzyme from up to 23 liters of packed erythrocytes at one time. An easily prepared affinity column bed material employing adenosine as the ligand was used as the final step in the purification. During elution from the affinity c...
~ The depletion process of copper ions from dilute solutions has been used as a model system to investigate the spouted bed cell with a three-dimensional electrode of conducting particles. Experiments under potentiostatic and galvanostatic conditions have been carried out. Results obtained indicate that the spouted bed cell has several favourable characteristics for application in metal recover...
