KINECTICS STUDIES OF ADSORPTION OF RR-120 DYE USING Spirulina platensis MICROALGAE AND COMMERCIAL ACTIVATED CARBON AS ADSORBENTS FROM AQUEOUS EFFLUENTS
نویسندگان
چکیده
Comparative study of the removal of the dye Reactive Red 120 (RR-120) from aqueous effluents from textile industry using microalgae Spirulina platensis (SP) and commercial active carbon (AC) were carried out. The batch adsorption systems were evaluated with respect to pH, agitation time, temperature and initial concentration of the dye. The maximum adsorption capacity for dye RR-120 were found at pH 2 and 298K. The general kinetic model was the most appropriate to explain the adsorption of RR-120 using SP and CA. The SP and AC adsorbents showed good performance for treatment of simulated textile industrial effluents by removing from 94.4 to 99.0% and from 93.6 to 97.7%, respectively, of dye mixtures in high saline concentrations.

Partial Replacement of Fishmeal by Lyophylized Powder of the Microalgae Spirulina platensis in Pacific White Shrimp Diets
An eleven-week feeding trial was conducted to evaluate the growth effect of partial replacement of fishmeal by the microalga Spirulina platensis in the diet of juvenile Pacific white shrimp Litopenaeus vannamei (Boone). The results clearly indicate that Spirulina platensis constitutes an effective food ingredient for shrimp. Growth rates of a Spirulina-fed group differed highly significantly (p...
