Amorphe und kristalline cer(IV)-phosphate als ionenaustauscher—IV Makrosorption, tracersorption und nuklidtrennungen an kristallinen cer(IV)-phosphatsulfaten

Electrical and thermal studies on poly(3-methyl thiophene) and in situ polymerized poly(3-methyl thiophene)cerium(IV)phosphate cation exchange nanocomposite

“…Cerium(IV) phosphates have received attention since the end of the 1960s because of their interesting properties such as cation exchange, intercalation, proton conductivity [32][33][34]. Thus, in this work, we have synthesized a new conductive nanocomposite of poly(3-methythiophene) (P3MTh) with cerium (IV)phosphate cation exchanger by in situ chemical oxidative polymerization technique.…”

Purification of Actinides from Small Cation Impurities Using Crystalline Ce(l V)-Phosphate-Sulphate as a Cation Exchanger

“…As with other known inorganic cation exchangers, e. g. zirconium phosphate, binding may be so strong, that elution of the ions sorbed can be brought about only by drastic measures which may sometimes cause decomposition of the ions exchanger [1,2]. The behaviour of lanthanides on Ce(IV)-phosphate-sulphate is known from our earlier work [4,5]. It is to be inferred from that work that in weak mineral acid solutions, actinides will not be sorbed.…”
