This paper describes the extraction properties of three kinds of new Calix[n]arene-Chitosan Polymer (n = 4, 6, 8) (C[n]CSP (n = 4, 6, 8)) which are soluble in chloroform. Through the two-liquid-phase method of lab of Martell and different spectrophotometry, extraction studies of Fe3+, heavy metal cations (Cd2+, Pb3+ and Hg2+), dichromate anions and rare earth metal cations (La3+, Ce3+ and Eu3+) were...
