Co Precipitation

To reduce costs and improve practicability, IMCS was synthesized through co-precipitation using steel pickling waste liquor and chitosan and Cu(ii) as template ions, which was then characterized by TEM, SEM, EDX, FTIR, XRD and VSM.

Coated Cotton

A new composite magnetic chitosan coated cotton (MSCC) fiber with 3-glycidyloxypropyltrimethoxysilane (GPTMS) as a crosslinking agent was prepared for the adsorption of C.I. Reactive red 194 from aqueous solution. The structure and morphology of MSCC fibers were analyzed by FTIR and SEM. The adsorption behavior of C.I. Reactive red 194 from aqueous solution onto MSCC fibers was investigated under various experimental conditions such as initial concentration of the dyes, temperature, pH and adsorb time. Experimental data indicated that the adsorption capacity of MSCC fibers on C.I. Reactive red 194 was higher in acidic rather than in basic solutions. A rise of temperature accelerates mass transfer of dyes into the MSCC fibers. The kinetics of the interactions was best described by pseudo-second-order mechanism.
