کاربرد ایزوتوپ پایدار کربن 13 در تجزیه هیدروگراف چشمه های کارستی
امروزه در مطالعات آب زیرزمینی در محیطهای کارستی بررسی و تعیین نقش بخش اپی کارست در ذخیره سازی و انتقال آب اهمیت فراوانی دارد. مطالعات بسیاری تاکنون انجام گردیده که با استفاده از اندازه گیری ایزوتوپهای 18O و D در طی یک واقعه ...
Selective cerium(III) cation detection by polymeric ion selective electrode based on 1,13-bis(8-quinolyl)-1,4,7,10,13-pentaoxatridecane
metal ions [1-3]. A cerium(III) cation selective electrode based on 1,13-
bis(8-quinolyl)-1,4,7,10,13-pentaoxatridecane (kryptofix5) incorporated into a poly(vinyl chloride) (PVC) membrane has been developed. The electrode
was prepared...

Polymeric membrane and coated graphite mercury(II)-selective electrodes based on 1,13-bis(8-quinolyl)-1,4,7,10,13-pentaoxatridecane as an excellent Ionophore
on 1,13-bis(8-quinolyl) -1,4,7,10,13-pentaoxatridecane(kryptofix5) as
an excellent sensing material is successfully developed. It is well established that some important features of the PVC membranes such as the properties...
Complexation and thermodynamic study of 1,13-bis(8-quinolyl)-1,4,7,10,13 -pentaoxatridecane with Hg2+ cation in mixed non-aqueous solvents
Cyclic polyethers(crown ethers) are selective complexing agents for the cations[1-3]. They are utilized to extract cations from aqueous solutions into
hydrophobic, nonpolar organic solvents and to carry these cations selectively through...
A Silver (I) Selective PVC Membrane Electrode Based on 1,13-Bis (8-quinolyl)-1,4,7,10,13-pentaoxatridecane as an Ionophore
A highly selective silver (I) electrode was prepared by incorporating 1,13-bis (8 quinolyl)1,4,7,10,13-pentaoxatridecane (kryptofix5) as a neutral ionophore into plasticized polyvinyl chloride (PVC) membrane....
