Preparation of U3O8 by Calcination from Ammonium Uranyl Carbonate Using Response Surface Methodology: Process Optimization
The parameters to prepare U3O8 by calcination from ammonium uranyl carbonate were optimized by using response surface methodology. A quadratic equation model for the value of total uranium and U4+ of triuranium octaoxide was built and the effects of main factors and their corresponding relationships were obtained. The statistical analysis of the results indi...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Contribution of lead from calcium supplements to blood lead.
We conducted a case-control study to determine the contribution of lead to blood from consumption of calcium supplements approximating the recommended daily intakes over a 6-month period. Subjects were males and females ages 21 to 47 years (geometric mean 32 years) with a geometric mean blood lead concentration of 2.5 microg/dL. They were subdivided into three groups. One treatment group (n = 8...
متن کاملRefining a Process
Unlike word processing, the changes involved in using rn have not concerned the program, but have instead involved the type of user, equipment, and environment, all of which have evolved through the years and into the 90s. This paper profiles the various changes and offers suggestions for future structure and encouragement in the use of lQX.
متن کاملThe Precipitation of Blood Calcium by Lead
The treatment of inoperable cancer by the intravenous injection of suspensions of lead has stimulated interest in the fate of this metal in the blood stream. The original metallic colloid of Bell (1) is very sensitive to oxygen, and by in vitro experiments Brooks (2) and Bischoff and Blatherwick (3) showed that there was little likelihood of any of the metallic lead reaching the cancer as such....
