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 best option from the list would be that the United Negro Improvement Association was "unconventional" compared with other similar institutions at the time, since it advocated for a variety of auxiliary stations and was highly nationalist in nature.
Answer:
the answer is c The meatpacking industry grew because railroads were used to deliver large quantities of meat to processing plants in major cities.
<span>False. Magellan did not successfully return to
Spain after his conquest. He was slain by a known Filipino Tribe Leader called
Lapu-Lapu. He was making deals with the tribe for assimilation but had
underlying motives that were eventually revealed to the leader which ultimately
led to his demise. </span>
Textbooks are the <span>best examples of a secondary source document useful in the study of history.
