AbstractThe sums involving Franck‐Condon overlap integrals are given in closed form for simple harmonic oscillator having the same potential field in both the ground state and the excited state. These sums are immediately related to the ones encountered in the theory of Raman scatterrin

摘要:

AbstractThe iron‐diethylenetriaminepentaacetic acid (DTPA) system has been investigated polarographically over thepH range 3–10 in the absence of maximum suppressor. The iron (III) complex is reversibly reduced at the dropping mercury electrode. Polarograms of mixtures of iron (III) and iron (II) yield a composite cathodic / anodic wave in the presence of excess DTPA. The half wave potential of the system is constant in thepH region 5.5–9, and from this the ratio of the stability of iron (III) DTPA to iron (II) DTPA has been evaluated. The stability constant of the ferric complex has been obtained from a spectrophotometric analyse of its dissociation equilibrium in 0.4–1.0Mperchloric acid medium at wavelength 380–520mμ. μ dependence of the acid dissociation constant of DTPA verified that the Davies quation can be extende

摘要:

AbstractA systematic study was made to prepare technetium‐99mgenerator for domestic uses in the fields of nuclear medicine and biological tracer work by using molybdenum‐99 produced by Tsing Hua Open‐pool Reactor (THOR). Alumina was used as generator bed and technetium‐99m was milked by physiologic saline solution. It was found that it is feasible to prepare technetium‐99m generator by which medically acceptable technetium‐99m solution can be obtained for practical a

摘要:

AbstractBy using iodine‐131 prepared in the radioisotope laboratory of the National Tsing Hua University, a systematic study was carried out to prepare iodine‐131 labelled human serum albumin (RISA) for domestic use as a radiopharmaceutical. Special emphasis was placed on the purification of RISA in an attempt to meet the specifications required by medical workers. The optimum conditions for radioiodination reaction and purification procedure are discussed in details. It was concluded that the RISA prepared in the Tsing Hua Laboratory is acceptable for radiopharmaceutical

摘要:

AbstractCation exchange behavior of actinium‐228 in mixed solvent system consisting of methanol‐thiocyanate‐water was studied with Dowex 50 resin. Solvent systems containing 50 to 90% methanol and concentration of thiocyanate from 1F to 5F were used. The distribution ratios of actinium between resin and the solutions were estimated by batch equilibrium and elution peak methods. By plotting these distribution ratios for each solvent system against the concentration of thiocyanate, different correlations were found. The difference may be attributed to the fact that the different species were absorbed by the resin. Feasibitity of using the mixed solvent system to the separation of actinium from thorium, was also exa

摘要:

AbstractThe fatty acids and the unsaponifiable matter in the root oil ofMaclura pomiferaRaf. were investigated. The root oil was saponified and the following fatty acids were identified: Myristic, oleic, and linolenic acid. Three crystalline substances; lupeol, β‐sitosterol and a new compound were isolated from the unsaponifiable matter of the oil. The NMR, UV and IR spectra of this new compound are report

摘要:

AbstractTen common dinitrophenyl amino acids were used to test the performance of polyamide layer chromatography for quantitative analysis. The polyamide layer is used as the stationary phase and U. V. photometric method is employed for quantitative estimation. The results show that high accuracy of quantitative analysis by polyamide layer can be achieved. Possibility of repeated use of polyamide layer was discussed also.
