Chelation of Trace Metals in Nutrient Solutions.
Plant nutrition studies frequently require nearly complete elimination of trace metals from the nutrient media in which the plants are to be grown. Conventional methods of purification by recrystallization and precipitation have been used for this purpose in some studies. These have proved more difficult and less effective than the adsorption technique developed by STEINBERG (11) and improved b...
متن کاملHeavy Metals and Chelation Therapy
Normal physiological function requires various minerals, including trace amounts of heavy metals such as zinc, copper and iron, as essential elements to maintain the metabolism. Heavy metals enter the body via food, drinking water, and even breathing air, but excessive levels can induce disorders and diseases. The past hundred years of industrialization and technological advances have brought e...
متن کاملChelation of toxic metals: current interests.
Chelation therapy has long been regarded as a suitable approach to the therapeutic and even prophylactic removal of potentially toxic metals from body tissues. And there have been apparent successes in some areas, but there are also needs for a better understanding of the underlying pharmacology and for the development of safer and more effective agents. There are currently three areas of inter...
متن کاملA simple plant nutrient solution purification method for effective removal of trace metals using controlled pore glass-8-hydroxyquinoline chelation column chromatography.
Column chelation chromatography on controlled pore glass-8-hydroxyquinoline was demonstrated to be a very efficient method for removing trace metal contaminants from concentrated macronutrient salt solutions used to prepare nutrient media. By using (63)Ni and (65)Zn radio-isotopes as tracers, controlled pore glass-8-hydroxyquinoline column packings were found to retain 99.9% of the radiotracer ...
متن کاملEDTA chelation therapy in the treatment of toxic metals
BACKGROUND: Metal induced toxicity with wide range of physiological, biochemical and behavioral dysfunctions was reported in many studies. The chelation has been used for treatment to toxic metals’ exposure for many years. In our current clinical study, we compared different chelation protocols and two forms of EDTA (sodium calcium edetate and sodium edetate) in treatments of toxic metal exposu...
