Resumen:
ABSTRACT:
New water-soluble metalpolymers of poly
(acrylic acid)s (AA) with different amounts of tin (3, 5,
10, and 20 wt %) were synthesized and characterized.
The materials were characterized by 1H NMR and FTIR
spectroscopy, X-ray diffraction (XRD), specific area by
isotherm of CO2, and thermogravimetry-differential scanning
calorimetry (TG-DSC). The synthesized material is
crystalline and shows an average crystal size 90130 nm
and has a high thermal stability (>200C). Texturally,
they are complexes of small specific area, which
decreases when the crystal size increases with the tin
content. Presumably, the Sn(II) ions coordinate through
2-4 carboxylate groups by a conventionally bidentate
structure; however, they are not symmetric. Studies have
been dedicated to support of tin in polymers to increase
its efficiency in eliminating pollutants. The tin-metal salt
is added to the poly(AA) matrix to increase its ability to
remove As(III) from an aqueous solution. The liquidphase
polymer-based retention technique is applied to
retain and separate contaminants from water. The analysis
of As(III) and As(V) species was made by combining
liquid high-resolution chromatographic coupled to
hydride generation absorption atomic spectrophotometer
(HPLC-HG-AAS). All indicated that As(III) was the predominant
species bound to the polymer complex for the
pH range 48. The polymers containing 10 and 20 wt %
Sn presented the highest retention of 70 and 90% As(III),
respectively.

is added to the poly(AA) matrix to increase its ability to
remove As(III) from an aqueous solution. The liquidphase
polymer-based retention technique is applied to
retain and separate contaminants from water. The analysis
of As(III) and As(V) species was made by combining
liquid high-resolution chromatographic coupled to
hydride generation absorption atomic spectrophotometer
(HPLC-HG-AAS). All indicated that As(III) was the predominant
species bound to the polymer complex for the
pH range 48. The polymers containing 10 and 20 wt %
Sn presented the highest retention of 70 and 90% As(III),
respectively.

crystalline and shows an average crystal size 90130 nm
and has a high thermal stability (>200C). Texturally,
they are complexes of small specific area, which
decreases when the crystal size increases with the tin
content. Presumably, the Sn(II) ions coordinate through
2-4 carboxylate groups by a conventionally bidentate
structure; however, they are not symmetric. Studies have
been dedicated to support of tin in polymers to increase
its efficiency in eliminating pollutants. The tin-metal salt
