In vitro release of citrate anions intercalated in magnesium aluminium layered double hydroxides

High-efficiency carbon-supported platinum catalysts stabilized with sodium citrate for methanol oxidation

“…3 shows the FT-IR spectra of sodium citrate and as-prepared Pt catalyst with sodium citrate. The pure sodium citrate is characterized by major peaks at 1594 and 1419 cm −1 assigned to the unsymmetrical stretching vibration and stretching vibration of COO − , and at 3454 and 3268 cm −1 to the stretching vibration of -OH in sodium citrate and -OH of the crystal water, respectively [22]. As shown in Fig.…”

Hybrid Inorganic/Organic Composites of Layered Double Hydroxides Intercalated with Organic Acid Anions for the Uptake of Hazardous Substances from Aqueous Solution

“…Meyn et al (1990) used the anion exchange method to prepare Mg-Al LDH composite materials with intercalated C 6 H 5 O 7 3-and C 4 H 4 O 6 2-, whereas Zhang et al (2004) prepared Mg-Al LDH intercalated with C 6 H 5 O 7 3-, C 4 H 4 O 5 2-, and C 4 H 4 O 6 2-through a unique method involving the dissolution of CO 3 •Mg-Al LDH to form the corresponding carboxylic acid followed by precipitation in basic solution. Tronto et al (2001Tronto et al ( , 2004 used coprecipitation to form Mg-Al LDH intercalated with C 6 H 5 O 7 3-. We prepared Mg-Al LDHs intercalated with C 6 H 5 O 7 3-, C 4 H 4 O 5 2-, and C 4 H 4 O 6 2-by coprecipitation via dropwise addition of a Mg-Al nitrate solution to citrate, malate, and tartrate solutions, respectively, at a constant pH of 10.5 and investigated the effects of the organic anion concentrations on the formation of the composites (Kameda et al, 2009a …”

Cephradine Intercalated Mg-Al Layered Double Hydroxide

“…Works on the intercalation of the various organic molecules into the hydroxide layers have been exploited for various purposes and application [14,15] in many different areas such as bioactive agent [10], medicine [15,16,17], catalyst [18], anti-inflammatory drugs, [19,20,21] urea biosensor and supports [22], and decolorizing agents [23]. The production and use of drug must be controlled to minimize the potential damage to the environment and public health.…”
