Table 1: Summary of the main characteristics of molecularly imprinted polymers (MIPs) in their application to the removal of As(V) and As(III) from water. Figure 3: Classification of the main features used for the creation of MIPs, as described in this review. ization (400 r/min, 323-343 K for 3 h) has been applied, using 1,12-dodecanediol-O,O-diphenyl-phosphonic acid (DDDPA) and 4-vinylpyridine (4-VP) as functional monomers, TRIM as a cross-linking monomer, AIBN as an initiator, toluene as a porogen, and Span 80 as an emulsifier, to form a novel mixed As(V)-Cr(III)-ion co-imprinted polymer (MICIP). The obtained results seem to be quite promising, with 200 nm clusters of near nano-size-imprinted polymer beads, quite a large surface area (309.2 m\({}^{2}\)/g), and satisfactory pore and micro-pore volumes (0.687 cm\({}^{3}\)/g and 0.03 cm\({}^{3}\)/g, respectively). The pore width was 1.75 nm and the adsorption capacity was 12 mg/g, with a pH = 5, demonstrating the satisfactory application of MIPs.
