Preparation of supported chitosan adsorbent with high adsorption capacity for Titan Yellow removal.

The supported chitosan (CS) adsorbent (FZCS) was successfully prepared by load CS on the BSCS supporter in this work. The adsorbent was characterized by elemental analysis, FT-IR, XRD, TGA, SEM and N adsorption-desorption techniques. The results showed the FZCS sorbent displayed the high removal rate (97.

Modification of chitin with high adsorption capacity for methylene blue removal.

Porous chitin sorbents (PChs) with different content of chitin, ranging from 0.9% to 3.5%, were prepared by gel method with CaBr·xHO/CHOH solution and characterized by FT-IR, XRD and SEM.

Hexaaqua-manganese(II) 4,4'-(1,2-dihy-droxy-ethane-1,2-di-yl)dibenzoate monohydrate.

In the title compound, [Mn(H(2)O)(6)](C(16)H(12)O(6))·H(2)O, the [Mn(H(2)O)(6)](2+) complex cation lies on a mirror plane, the 4,4'-(1,2-dihy-droxy-ethane-1,2-di-yl)dibenzoate anion is located on an inversion center and the solvent water mol-ecule also lies on a mirror plane. Extensive O-H⋯O hydrogen-bonding inter-actions between the cations, anions and water mol-ecules stabilize the three-dimensional network.
