Journal ArticleDOI
Equilibrium, kinetics, mechanism, and process design for the sorption of methylene blue onto rice husk
V. Vadivelan,K. Vasanth Kumar +1 more
TL;DR: Analysis of sorption data using a Boyd plot confirms that external mass transfer is the rate limiting step in the sorption process.
Journal ArticleDOI
Langmuir–Hinshelwood kinetics – A theoretical study
TL;DR: In this article, it was shown that it is impossible and inappropriate to approximate the Langmuir-Hinshelwood kinetics to zero-order kinetics, and therefore, it is not possible to approximate it to zero order kinetics.
Journal ArticleDOI
Modeling the mechanism involved during the sorption of methylene blue onto fly ash.
TL;DR: Analysis of sorption data using a Boyd plot confirms the particle diffusion as the rate-limiting step for the dye concentration ranges studied in the present investigation (20 to 60 mg/L).
Journal ArticleDOI
Linear and non-linear regression analysis for the sorption kinetics of methylene blue onto activated carbon
TL;DR: Investigation showed that it is inappropriate to use a type 1 and type pseudo second-order expressions as proposed by Ho and Blanachard et al. respectively for predicting the kinetic rate constants and the initial sorption rate for the studied system.
Journal ArticleDOI
Removal of methylene blue by mango seed kernel powder
TL;DR: In this paper, a batch experiment was carried out for the sorption of methylene blue onto mango seed kernel particles, where the operating variables studied were initial solution pH, temperature, adsorbent mass, initial dye concentration and contact time.
