Abstract

This study proposes an easy and cheap technique to get rid of dangerous Malachite Green (MG) dye from waste material by victimization carbon from walnut shells. The simple treatment was carried out by heating at temperature in which was set to the best carbonization degree to arrange carbon from these shells; thus, the temperature was set to 200 °C. Optimum conditions for sorption like the quantity of adsorbent, contact time, particle size of adsorbent, pH scale and initial MG concentration were conjointly examined. The results showed that the simplest removal was obtained once victimization 1 g of carbon with particle size 150 μM and time contact 150 min. However, the sorption of the dye was not affected by the pH except the sorption was very low at pH = 2. The removal potency was high approximating 99.53%. The results conjointly showed that the sorption equilibrium of MG onto carbon that was ready from the walnut shell has been evaluated via Langmuir and Freundlich models.

Abstract

The research is included studying and designing micro flow injection system which is characterized with rapidity, simplicity, and low cost for the determination of green malachite dye. The study of flow rate of carrier stream, repeatability, dispersion coefficient, and calibration graph are conducted. It is found that the optimum conditions for the determination of mentioned dye are flow rate 4.200 mL/min, sampling rate 102 sample/h, limit of detection 0.05 ppm, linear range (0.05-18.00) ppm with linearity (R2=0.9700), RSD is 0.355, the repeatability for seven successive injections is studied for the two concentrations 5 ppm and 12 ppm, and the dispersion coefficient values are 1.73 and 1.28 at the two concentrations 2 ppm and 9 ppm respectively.
