Citrus limetta peel is an effective cheap adsorbent the removal of methylene blue dye. Adsorption of methylene blue on to citrus limetta peel is spontaneous and endothermic. The adsorption is best represented by Langmuir adsorption isotherm. The adsorption follows pseudo-second order kinetic model.

How do you remove methylene blue?

Methylene blue washes off with pure ethyl alcohol, and with 70% isopropyl alcohol (rubbing alcohol), from the healthy skin with some effort but those blue splotches on dead skin will remain.

How do you get blue dye out of water?

You can also add vinegar to the boiling water and stick a piece of white yarn in it. It will collect the blue dye and turn blue, leaving the water and vinegar either clear or a milky color as a result.

How are dyes removed from water?

There are three major technologies available to remove dyes from water (i.e., oxidation, adsorption, and flocculation−precipitation). Only recently membrane separation technology has been used for the separation of dyes from water.

Does carbon remove methylene blue?

An activated carbon was prepared from pea shells and used for the removal of methylene blue (MB) from aqueous solutions. The influence of various factors such as adsorbent concentration, initial dye concentration, temperature, contact time, pH, and surfactant was studied.

Methylene blue (MB) is a cationic dye that exists at a large scale in the textile wastewater which is discharged into the nearby environment without proper management, particularly in developing countries including Ethiopia.

Is methylene blue toxic to environment?

Toxicity of Methylene Blue

MB is toxic, carcinogenic, and non-biodegradable and can cause a serious threat to human health and destructive effects on the environment [100,101].

Is methylene blue a pollutant?

Methylene blue (MB) is categorized as an organic dye (OD) released as effluents after various industrial activities and is one of the most abundant pollutants in the aquatic environment. Significantly, because of its potential toxicity, removing MB from wastewater has been a matter of necessity in recent times.

The adsorption is best represented by Langmuir adsorption isotherm. The adsorption follows pseudo-second order kinetic model.

What is the pH of methylene blue in water?

The same trend has been supported by the literature for MB sorption. (30,31) Consequently, the pH 7.0 has been reflected to be the optimum level because at this pH the maximum sorption capacity (123 ± 2.5 mg/g for BC and 163 ± 4.2 mg/g for DDAB-BC) has been observed.

Does activated carbon remove color?

Activated carbon is the greatest developed and one of the most efficient processes available for the removal of most organic and some inorganic materials from wastewter. Activated carbon is also capable of removing color from water.

What is the methylene blue number of activated carbon?

The methylene blue number is defined as the maximum amount of dye adsorbed on 1.0 g of adsorbent. Adsorption experiments of the molecules of methylene blue are easy and habitually done to characterize activated carbons with the purpose of obtaining information on the adsorption capacity of the materials.

Removal of Methylene Blue (MB) from aqueous solutions is studied using a raw Algerian kaolin sample as a low-cost adsorbent. The effects of pH, contact time, dye concentration and temperature are all taken into consideration. The adsorption kinetics results are adjusted to best fit the pseudo-second order model.
