Description

A study has been made of the time and temperature required to anneal Teflon and Fluorothene. It has been found that, by proper annealing, the strains my be removed and cold-flow prevented. The disk stopcocks prepared with annealed plastics have not developed leaks on standing. A description is given of the modified slug-dissolver heating unit which has been installed in the Bismuth-II Process Line. Work has been continued on the absorption spectra of bismuth in hydrochloric acid solutions. Two methods have been described for the interpretation of absorption spectra data. The transmission curve of the Evelyn colorimeter filters have been ... continued below

Work has been continued on the absorption spectra of bismuth in hydrochloric acid solutions. Two methods have been described for the interpretation of absorption spectra data. The transmission curve of the Evelyn colorimeter filters have been measured on the Cary recording spectrophotometer. The resulting curves should aid in the selection of the proper filter for a given calorimetric analyses. A brief outline for the proposed method of decontaminating platinum has been presented.
