Abstract: Antistatic agents for reducing and eliminating static electric charges on resins, particularly acrylic resins, including an antistatically effective amount of at least one substituted imidazolinium salt of alkylbenzene sulfonic acid having the formula: wherein R1 and R2 are the same or different and are alkyl groups having 6 or more carbon atoms. Also contemplated are methods, compositions and articles of manufacture which include the above mentioned antistatic agent and are added to or on the resins and further contain fatty acids or optical brighteners.

Abstract: A process for producing substantially radio-impurity-free Bi-212 is disclosed. An acidic feed solution containing Pb-212 is contacted with an extraction medium to bind the Pb-212 thereto. The extraction medium is rinsed with a second acid solution to remove impurities therefrom, leaving a substantially impurity-free Pb-212-laden extraction medium The Pb-212 grows on the extraction medium to form Bi-212 by radioactive decay. The Bi-212 is then eluted from the extraction medium with an acid solution to form a substantially radio-impurity-free Bi-212 acid solution. An apparatus for carving out this process and a process for the therapeutic use thereof are also disclosed.

Abstract: Biological treatment process removes free and metal complexed cyanides, and thiocyanate through oxidations. Even high concentrations of these pollutants are workable. Toxic heavy metals are absorbed and adsorbed within a biofilm. This process has been adapted to and performs well at high cyanide concentrations (e.g., even above about 100 mg/L and high pH (e.g., even higher than about 9.5). Mixed cultures of adapted strains of Pseudomonas are utilized to perform biological oxidation within the system. End products of oxidation include carbonates, sulfates, and nitrates. The pH is neutralized by metabolism of, or by, intermediate reaction products. The biological processes can be utilized as a pretreatment or post-treatment process in conjunction with chemical processes.

Abstract: Cyanides, thiocyanates and metal cyanide complexes present in an aqueous solution can be biologically degraded by certain mutant strains of the species Pseudomonas paucimobilis. Such microorganisms are useful in the biological treatment of cyanide-containing wastewaters.Pseudomonas paucimobilis mudlock was deposited at the ATCC on Nov. 3, 1982, and granted accession No. 39204.
