1. Water-soluble symmetrical heavy-metal complex compounds of a metal-free azo compound of the general formula (1) see diagramm : EP0082415,P31,F1 in which : m is the number 1, 2 or 3 ; n is the number zero or 1 ; D is the radical of a diazo component of the benzene or ...
As the adsorbed toxic lead and cadmium ions are easily removable by a decrease of pH the determination of the soluble form of toxic metal is not sufficient for an assesment of the environmental hazards. The potential bioavailable compounds are gathered by an acidification to pH 3 prior to ...
1. A method of immobilizing heavy metal in a free flowing dry or wet waste which maintains its free flowing nature after immobilizing treatment, said method consisting essentially of: contacting a waste with an effective amount of water insoluble immobilizing agent to reduce the leaching of the ...

- 《Water Research》 被引量: 517发表: 2001年 Process for the removal and recovery of heavy metals from aqueous solutions A process is provided for reducing the concentration of water soluble ionic heavy metal species and sulfate ions in aqueous waste solutions containing the same. The process ...
Ionic liquids, as the environment-friendly solvents, have been applied in the analytical process owing to their unique physicochemical properties. This review summarizes the applications of ionic liquids in the determination of heavy metal ions and organic pollutants in water samples. In addition, some...
It is desing-ed specially for removing or reducing chlori-ne and water -soluble heavy metals. It could controls scale,bacteria and algae,even in hot water. KDF 55 Media could produce eletricity exchange reaction and remove heavy metal ,cop-per,lead,mer-c...
60% and 5. 17%,respectively.The morphological changes of the four kinds of heavy metals in phyto-mimic remediation are not the same. The reduction rate of soil Zn and Cr contents of different forms is as follows: acid soluble reducible oxidizable residual fraction; while the reduction rate ...
In order also to make the solids separating from the slag remover difficult to elute, these are sprayed with sulphuric acid or bicarbonate solutions, as a result of which the soluble heavy metal salts situated on the surface are converted into sparingly soluble carbonates or sulphates....
