What is it about?
This paper presents the study results on the adsorption of Methylene Blue (MB) by composites made from montmorillonite (MMT) and chitosan (CS). The aim is to develop an alternative material as MB adsorbent therefore the mechanism of MB adsorption by the MMT-CS composites was studied, that is through the adsorption efficiency, the effect of contact time on adsorption capacity, and the adsorption kinetics.

Why is it important?
MB is a non-biodegradable, toxic, and mutagenic material. This substance, known as textile factory waste, must be processed before being released into the environment to prevent pollution and interfering with health. In this research, MB dye waste was processed through an adsorption process by MMT-CS composites. This study is important to gain understanding about the effect of the composite component composition on the mechanism of the adsorption process.
Perspectives
I hope this article brings an understanding on the mechanism of MB adsorbent by MMT-CS composite, where it was obtained that the addition of CS content of the composite increases the adsorption efficiency and rate constant in the pseudo-second order adsorption mechanism scheme. Hopefully the use of MMT-CS composite can as adsorbent for removing MB dye can be developed further.
