SODIUM DODECYL SULPHATE MODIFIED IRON FILINGS FOR THE REMOVAL OF NAPHTHOL-AS DYE POLLUTANT FROM AQUEOUS ENVIRONMENT
نویسندگان
چکیده
This study investigates the removal of naphthol-AS dye from aqueous solutions by SDS-modified adsorbents under various experimental conditions. Results imply that adsorption process was highly pH-dependent and optimum pH for occurred at 6.0, having maximum efficiency 91 %. Adsorption Naphthol-AS on adsorbent fitted better into second order kinetic model capacity found to be 4.803mg g−1. Equilibrium isotherms were best described Langmuir isotherm with high-correlation coefficient value. The results infer iron filing is a promising dyes wastewater.

In this study, the adsorption behavior of anionic dyes from aqueous solution onto mesoporous carbon material (CMK-1) and modified with polymer (PANI/CMK-1) has been investigated as a function of parameters such as adsorbent dose (0.08-0.8 g/L), solution pH 3–10, contact time and initial concentration (10-100 mg/L). The influence of these parameters on the adsorption capacity has been studied us...
متن کاملSodium dodecyl sulphate electrophoresis of wheat gliadins.
Polypeptide chain weights of a-, 8and y-gliadin fractions have been estimated by polyacrylamide gel electrophoresis in the presence of mercaptoethanol and sodium dodecyl sulphate. Values lie in the range 32 000 to 44 OOO. When available data on the amino acid analyses were adjusted and compared, significant similarities emerged. It is suggested that these gliadins contain a minimum of 4 cystine...
