Groundwater contamination by toxic metals and organic compounds is a serious environmental and public health problem (Crini 39). Many of the common contaminants in wastewater are known to be toxic or carcinogenic. Common groundwater contaminants include heavy metal ions, aromatic compounds, and dyes. Additionally, heavy metals are not biodegradable and tend to bioaccumulate, leading to various diseases and disorders. Mercury and cadmium are among the most toxic metals and are very damaging to the environment. Additionally, chromium (VI) is a wide-spectrum toxin, as it is toxic to bacteria, plants, animals, and humans. Organic compounds in groundwater are ...

Abstract

The research is dedicated to studies of activated carbons performance in the wastewater treatment process of dye removal. The experiment was performed to assess the efficiency of the commercial activated carbons (F100, F600, F820, SGL 8×30, CAL, AP4-60, OLC12×30) in adsorption process for Dylon Burlesque Red removal. The effect of pH, type of activated carbon, dye, contact time, and salinity was studied. The experiments were performed by measuring the absorbances of the solutions before and after contact with the activated carbon. The absorbance was evaluated with UV-vis spectrometry. The adsorption of the dye took place on all ...

Chapter 1

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Food is a basic commodity needed to sustain life and as such, it must be safe to eat. Despite the innumerable controversies that abound regarding the ingredients and additives in our food and sage advice from many professional sources and health gurus arguing to the contrary, this paper will support the thesis that, for most people, our food supply is safe. While accepting that prepared foods may contain additives and preservatives, these are necessary to allow manufacturers to bring food safely into our homes. Preservatives and additives are necessary to ensure that our food supply is safe, but ultimately ...

4 – Nitroaniline

INTRODUCTION

4-Nitroaniline is an organic nitro aromatic compound. It is a yellow powder with a pungent odor and is highly soluble in hot water, methanol, ethanol, acetone etc (Lide 1994). Its chemical formula is C6H6N2O2. It has the following chemical structure: (Courtesy: PubChem 2016) It is also known as P-Amino nitrobenzene, P-Nitraniline or Benzene amine (PubChem 2016). It explodes on decomposition to emit toxic nitrogen oxides (Lewis 1996). 4-Nitroaniline is used in the manufacture of textile dyes such as the red azo dyes. It is also used in preparation of antioxidants, fuel additives, pesticides, pharmaceuticals and poultry medicines ( ...

Introduction

Panter-Brake (202) asserts that most people use beauty products with the assumption that these products have undergone thorough testing to ensure their safety before they reach the consumers. The assumption comes because the government is known to regulate most consumer products such as food, water, among others. Therefore, people expect that FDA ensures the health and safety in the cosmetic industry so as to protect consumers. Unfortunately, little power has been given to FDA in regulating cosmetics’ ingredients. The people who govern cosmetic industry are responsible for ensuring safety of the beauty products. Several studies reveal that consumer safety ...

George Washington Carver was an African American who was born into slavery. At the end of the civil war, he got his freedom although however he still lived in his former boss’s house since he was an orphan. He educated himself by doing odd jobs and later earned a Master’s degree in horticulture.
