The kinetics of calcite dissolution in the presence of calcium chelating agents was investigated over the pH range of 3.3-12 using a rotating disk apparatus. The results show that the rate of dissolution is increased significantly by the presence of chelating agents such as CDTA, DTPA, and EDTA. The
The effect of two new chelating agents-Tiron (4,5-dihydroxy-1,3-benzene disulphonic acid disodium salt) and succinic acid-on the mobilization of beryllium was studied. Animals were exposed to beryllium nitrate (1 mg kg -1 i.p.) daily for 21 days. Administration of beryllium nitrate showed a marked d
## Abstract Polythiosemicarbazides react with acqueous Cu^+2^ solutions with formation of polymeric chelates, for which the following structure is typical: The adsorption of Cu^2+^ by the polymer proceeds selectively and in preference to Fe^3+^, Zn^2+^, W^6+^, Al^3+^, Be^2+^, Cr^3+^, UO~2~^2+^, Ni
