“…The percentage removal increased almost linearly with increased of dosage probably implying that the amount of LDH-MAN 4 sites also increased. This result was similar as reported by other researcher 5,6 which consisted well in the paper.…”

“…The interlayer spacing of the sample corresponding to the (006) plane was found to be 4.5Å. The result is similar to the study reported previously 5 , in which the XRD pattern corresponds to that LDH; the peaks are sharp signifying high crystallinity and increase as increase of LDH-MAN ratio. Layered double hydroxides (LDH-MAN) at ratio 4 was subsequently chosen as adsorbent for removal of sunset yellow FCF.…”

“…Species that carry negative charges account for a large part of water in the water systems 4 . The LDH's anion exchange ability, large surface area and regeneration ability ensures that this adsorbent can be effectively utilized in wastewater purification 5 . Since inexpensive cost of synthesis, stability and variety of color, used of synthetic dyes increasingly in dyeing, paper and pulp, textile, rubber, plastics, cosmetics, pharmaceutical, food and other industrial applications 6,7 .…”

Abstract:The potential feasibility of layered double hydroxides for removal of sunset yellow dye FCF from aqueous solution was investigated. The effects of various experimental parameters such as contact time, solution pH, dye concentrations and adsorbent dosage were investigated. The extent of sunset yellow FCF dye removal increased with the increased in contact time and amount of layered double hydroxides used however the percentage removal was decreased with the increased in pH and dye concentrations. Adsorption data was better fitted to the Langmuir isotherm. The results in this study indicated that layered double hydroxide was an attractive adsorbent for removing sunset yellow FCF dye from aqueous solution.

“…Several studies have reported on the use of layered double hydroxides as an adsorbent for the preservation of aqueous environments, such as treatment of coloured water [7,8], treatment of water polluted with heavy metals [9,10], and as nitrogen oxide storage [11]. The adsorption properties of layered double hydroxides toward metal cations can be improved by intercalating layered double hydroxides with metal chelating agents such as tartrate [5].…”

Layered double hydroxide intercalated with tartrate (tartrate-Mg-Al) was used as an adsorbent to remove lead ions from aqueous solutions. The effects of various optimization parameters such as contact time, solution pH, lead ion concentrations, and adsorbent dosage were investigated by the use of Response Surface Methodology (RSM). The Response Surface Methodology (RSM) based on a four-level four-variable Central Composite Rotatable Design (CCRD) was employed to evaluate the interactive effects of the various optimization parameters. The parameters were contact time (6–10 h), solution pH (1–3), adsorbent dosage (0.06–0.1 g), and lead ion concentrations (10–30 mg/L). The percentage of lead ions removal for each of the parameters studied was determined by Inductively Coupled Plasma-Optical Emission Spectrophotometer. Simultaneously by increasing contact time and amount of dosage of tartrate-Mg-Al used the percentage of lead ions removal from aqueous solution will increase; however, the percentage removal decreases with an increase in pH and concentrations of lead ions. The experimental percentage removal recorded under optimum conditions was compared well with the maximum predicted value from the RSM, which suggest that Central Composite Rotatable Design of RSM can be used to study the removal of lead from aqueous solution by the use of tartrate-Mg-Al as an adsorbent.
