The extraction of aqueous Cu(II) ion into chloroform were conducted by using N,N-bis(2-hydroxybenzyl)-propylenediamine(BHPD), N,N-bis(2-hydroxybenzyl)-diethylenetriamine(BHDT), N,N-bis(2-hydroxybenzyl)-triethylenetetraamine(BHTT), and N,N-bis(2-hydroxybenzyl)-tetraethylenepentaamine (BHDP) as ligands. The method is based on the formation of Cu(ll)- ligand complex, which is extractable into chloroform from an aqueous solution at pH 8 over by shaking for 1h. The absorbance were measured at 614nm Cu(ll)-BHPD, 599nm Cu(ll)-BHDT, 605nm Cu(ll)-BHTT, and 626nm Cu(ll)-BHTP. The Iigand-to-Cu(ll) ion ratio, the relationship between extractability and pH of the aqueous phase were examined.

Stability constants for the complexes of multidentate N,O-Schiff base ligands (bis-(salicylaldehyde)ethylendiamine(SED), bis-(salicylaldehyde)propylen diamine(SPD), bis-(salicyl -aldehyde)diethylenetriamine(SDT), and bis-(salicylaldehyde)triethylenetetraamine(STT) with Mn(II) and cd(II) were determined by a potentiometric method in a 70% dioxane-30% water mixture respectively. Stability constants for the complexes increased in the order of SPD < SED < SDT < STT with the increasing number of donor atoms employed.

The tetradentate ligands containing nitrogen and oxygen, 1,7-bis(2-Phenol)-2,6-diazaheptane(BPDP), 1,7-bis(5-bromo-2-Phenol)-2,6-diazaheptane(5-BrBPDP),1,7-bis(5-chloro -2-Phenol)-2,6-diazaheptane(5-CIBPDP) have been synthesized as their dihydrochloride salts. The protonation constants and stability constants of Co(II), Ni(II), Cu(II) and Zn(II) complexes have been determined by potentiometry. The calculation of contants were accomplished by PKAS and BEST programs introduced by Martell. The stability constants for complex is increased by substitution effect of benzene ring for BPDP > 5-Br-BPDP > 5-Cl-BPDP. The order of stability contant for the transition metal ions is Co(II) < Ni(ll) < Cu(II) > Zn(II) which follows the Irving-Williams series.

The polystyrene supported amines resin and their copper( II ) complexes have been synthesized and studied for catalytic action of the decomposition of hydrogen peroxide. The resins and their complexes were charactized by elemental analyses and infrared spectrometry. The rate-determining step of the decomposition of hydrogen peroxide with polystyrene supported amines such as diethylenetriamine, triethylenetetramine, tetraethylenepentamine and pentaethylenehexamine were determined by iodometry method. Lengths amines have a infuence on the rate of hydrogen peroxide decomposition. The oxidation of polystyrene supported amines with hydrogen peroxide were increased with increasing the number of nitrogen of amines.

The colorimetric determination of Cu(II) ion by using the polydentate schiff base ligands Bis-(salicylaldehyde)-diethylentriamine(BSDT), Bis- ( salicylaldehyde) -triethylenetetramine (BSTT), and Bis-(salicylaldehyde)-tetraethylenepentamine(BSTP) have been developed. The schiff bases and their Cu(II) complexes were obeyed to Beer's law in the concentration range 1.0X 10-3-4.OX 10 3M. The molar extinction coefficients of the Cu(II) complexes are low, and therefore the sensitivity is relatively low. Cu(ID was determined in the presence of univalent ions and bivalence cation ions but oxlate, EDTA, Fe(II), Fe(III) and Co(II) were interfered.
