Answer:
This work studies the adsorption of colored compounds in cane juice using a food-grade macroporous adsorber resin without functional groups. The adsorption equilibrium was studied through the adsorption isotherms at 30, 40, and 50 ℃. The absorbance at 420 nm was used to measure the concentration of colored compounds, which enables correlation of the residual concentration with the adsorbed concentration. Furthermore, the efficiency of the adsorption process was studied, from which it was observed that there was an improvement in efficiency with increasing resin content, while the increase in temperature was less important in the process. The kinetic study was performed using the Ibarz model and intraparticle diffusion model, which correctly account for the kinetics of the adsorption process. The adsorption kinetic constant was always greater than the desorption kinetic constant, indicating that the adsorption step predominates over the desorption step.Explanation:
The first two battles were the Battles of Lexington and Concord, fought on April 19, 1775 and they were located in Massachusetts.
Fear, its a simple and very effective tactic that can almost always work. Everyone has something they're scared of, and it isn't hard for governments to figure that out.
The Muslim troupes were led by Saladin, the first Sultan of Egypt and Syria and the finder of the Ayyubid dynasty.
Plessy was a citizen who claimed to be seventh eights Caucasian and only one eighth Black. He was imprisoned and trial in a criminal court after an incident that took place while in New Orleans, in 1896, when he tried to board a car designated for hite people. He was denied a seat in the car for white people and urged to take a seat in the car for black people. As Plessy refused on the basis of his predominantly Caucasian race, the train staff arrested him, and then he was put in the parish jail. He was charged with criminal counts, but Plessy requested his case to be presented to the Supreme Court for he deemed there had been violations of the Thirteen and Fourteenth Amendments (abolition of slavery and equal treatment).
The Supreme Court's opinion stated that the treatment based on "equal but separated" did not conflict with the Thirteenth Amendment, for this amendment only protected citizens from being enslaved or forced to involuntary servitude, and no conflict was found with the Fourteenth Amendment since it enforced equality, but it did not specify under which terms. Therefore, the decision of the Supreme Court supported the doctrine "equal but separate" and segregation as well.
