Any combination of these four anions may be prepared. Using a graduated Beral-type pipet, add 2 mL of each ion selected to a 13 X 100 mm test tube. Add distilled water to give a total volume of 8 mL. Stopper the test tube. A matrix of combinations, similar to the cation unknowns, can be generated for the anions. |Unknown No. |Cl- |CO32- |NO3- |SO42- | |1 |X |X |X | | |2 | |X |X |X | |3 |X | |X |X | |4 |X |X | |X | |5 |X | | |X | |6 | |X | |X | |7 | |X |X | | |8 |X |X | | | |9 |X | |X | | |10 |Show MoreRelatedTitanium Cerium Ferrite ( Tcf ) Was Prepared By A Simple Solvothermal Method5630 Words   |  23 Pagesa spontaneous and endothermic nature of process. The highest values of uranium desorption was achieved using 0.1 M HNO3 as the desorbing agent. The results indicate that TCF has potential as an adsorbent for sorption U (VI), using a simple, fast separation method for removal of uranium ions from aqueous solution. 1. Introduction Uranium is one of the most dangerous heavy metals in the environment because
