1. Result and discussion 1.1. Characterization of PUF and removal of Fe+3 on PUF 1.1.1. Characterization of PUF 1.1.1.1. Hydrolysis of white PUF using HCl The mass lost after 24 h in HCl concentration by the PUF was 0.45%. was i.e., with increasing acid concentration and some groups of the PUF the percentage loss of mass increased were hydrolysed. The cube shape of PUF was affected by acid washing i.e.the size of the cubes became smaller and they packed more closely together (Moawed, 2008). 1.1…

Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…

Green architecture is an approach to building, also known as green building or construction or even sustainable building has become more popular in the last 25 to 30 years, is the practice of creating an environmentally responsible that has the structure and resource effect throughout a building lifestyle from design, construction, operation, maintenance, renovation and deconstruction. Green building are designed to make the classical buildings concern about the economy, utility, durability and…

The FTIR spectrum of PVA/CS nanofiber was shown in Fig. 1(a). The band at 3255.32 cm−1 was corresponded to -OH stretching and the peaks at 1025.6 and 1450.04 cm−1 for the -C-O band. The peaks at 3445.32 cm-1, 2965 cm-1, 1640.01cm-1, 1598.7 cm-1, and 1361 cm-1 are due to amine NH symmetric vibration, C-H vibration, deformation vibration of the absorbed water molecules, stretching vibration of amino group of chitosan and vibration of C-H, respectively. The peaks at 890.1 and 1100 cm-1 was…

Shale of the Appalachian Basin With various depositional environments and the understanding of sea level change, the Appalachian Basin formed by the collision of tectonic plates and sediment accumulation under the Earth’s surface. The Appalachian Mountains reveal subsidence belts, faulted marine sedimentary rocks and other geologic rocks in these tectonic settings. The Basin exists in the northeastern states of North America. This large rock formation exhibits collisional tectonics with modern…

What the frack is fracking and why it should be replaced with alternative energy Hydraulic fracturing, or “fracking”, is the extraction of natural gas from deep underground shale using vertical (“conventional fracking”) and horizontal (“unconventional”) drilling. According to C. Mooney (The Truth About Fracking) conventional fracking has been used since the late 1940’s; it involves drilling a vertical well into a layer of shell and pumping chemically treated water and sand at extremely high…

Clean Water Act was passed in 1948 when it was called the Federal Water Pollution Control Act. The act was broadened in 1972 when it then began to go by the name of the Clean Water Act. Due to this act, the Environmental Protection Agency made wastewater standards for industries and standards for the quality of surface waters. Unless a permit was obtained, this act made it illegal to discharge pollutants into water due to contamination (“Summary of the Clean Water Act”). The Comprehensive…

“We do not own the earth; we borrow it from our children.” I believe this Cherokee saying that I received from an interview with the University of Tennessee 's Dr. Gregory D. Moore truly stands for what an environmental engineer is, yet it does not completely sum up what exactly one is. An environmental engineer is a paid and educated worker for the world who works full-time in multiple environments in order to receive the benefits of protecting the planet for others (Bureau of Labor Statistics)…

Alexander Yuryevich “Sasha Pichuskin was born on April 4,1974 in Moscow, Russia. Pichushkin lived with his mother and sister in a small apartment. He slept on a couch while his mother slept on a queen size bed.He grew up on Khersonskaya Street.His father was not in his life he left the family when Alexander was one years old. When Alexander was four years old that was when his life changed. At the age of four he fell off a swing and had brain damage from that. He became impulsive and hostile.…

Watershed pollution possess an environmental problem for many areas across the world. One example is the Buffalo National River Watershed. Recently, an industrial hog farming complex has moved near the Buffalo National River and in the watershed for this river system. Industrial hog farms create tremendous amounts of hog waste that pose a threat to the creeks and rivers that make up the surrounding watershed. Can the government and local conservation groups protect this beautiful ecosystem, and…
