Palladium(II) Recovery from Hydrochloric Acid Solutions by N,N′-Dimethyl-N,N′-Dibutylthiodiglycolamide
N,N′-dimethyl-N,N′-dibutylthiodiglycolamide (DMDBTDGA) has been synthesized, characterized, and is investigated in this work as a potential liquid-liquid extractant for palladium(II), platinum(IV), and rhodium(III) from hydrochloric acid solutions. Pd(II) is the only ion which is efficiently removed by DMDBTDGA in toluene from 1.5 M to 4.5 M HCl, but it is not extracted from 7.5 M HCl. Pd(II) s...

متن کاملThe oxidation of NN-dimethyl-p-phenylenediamine by oxidizing agents and by caeruloplasmin.
1. The oxidation of NN-dimethyl-p-phenylenediamine (DPD) by inorganic oxidants and by caeruloplasmin was studied. Some experiments were also made with NNN'N'-tetramethyl-p-phenylenediamine (TPD). 2. E(mM) (550) of the first free radical oxidation product of DPD (DPD(+)) was 9.8 and E(mM) (563) of the corresponding product of TPD (TPD(+)) was 12.5. 3. The non-enzymic decomposition of DPD(+) was ...
متن کاملpi NN coupling constants from NN elastic data between 210 and 800 MeV.
High partial waves for pp and np elastic scattering are examined critically from 210 to 800 MeV. Non-OPE contributions are compared with predictions from theory. There are some discrepancies, but sufficient agreement that values of the πNN coupling constants g 2 0 for π 0 exchange and g 2 c for charged π exchange can be derived. Results are g 2 0 = 13.91 ± 0.13 ± 0.07 and g 2 c = 13.69 ± 0.15 ±...
متن کاملExtraction of the pi NN coupling constant from NN scattering data.
We reexamine Chew’s method for extracting the πNN coupling constant from np differential cross section measurements. Values for this coupling are extracted below 350 MeV, in the potential model region, and up to 1 GeV. The analyses to 1 GeV have utilized 55 data sets. We compare these results to those obtained via χ mapping techniques. We find that these two methods give consistent results whic...
