Barium and Radium Complexation with Ethylenediaminetetraacetic Acid in Aqueous Alkaline Sodium Chloride Media
The speciation of Ra2+ and Ba2+ with EDTA was investigated at 25 °C in aqueous alkaline NaCl media as a function of ionic strength (0.2-2.5 mol·L-1) in two pH regions where the EDTA4- and HEDTA3- species dominate. The stability constants for the formation of the [BaEDTA]2- and [RaEDTA]2- complexes were determined using an ion exchange method. Barium-133 and radium-226 were used as radiotracers ...
متن کاملTitanium complexation with fluoride and chloride in supercritical aqueous fluids
The high field strength elements (HFSE, i.e. Ti, Zr, Hf, Nb, Ta, W, Th) reside in minerals that are traditionally considered to be nominally insoluble in aqueous fluids, but in recent years experimental and field-based evidence to the contrary has been presented. Here, first principles molecular dynamics simulations are used to demonstrate that at low concentrations both fluoride and chloride f...

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولEquilibrium Constants of the Complexation of Molybdate Ion with para-Sulfonatocalix [4] arene in aqueous media
The complexation of sodium molybdate with para-sulfonatocalix [4] arene was studied in thetemperature range from 20 to 40 °C and pH = 5.8 by spectroscopic method in water solution. Thestability constants of complexes were calculated by the multiwavelength analysis of spectral datausing SQUAD program. The equilibrium constant, spectroscopic data, molar absorptivities andconcentrations of all spe...
متن کاملRadium-223 Chloride
In the last few years, the treatment of castration-resistant prostate carcinoma (CRPC) has changed completely. The approval of docetaxel and subsequent investigation in this field have led to development of new agents that have demonstrated an improvement in overall survival in the post-docetaxel setting, such as cabazitaxel and abiraterone. Radium-223 chloride is a radioisotope that has recent...
