Over the last 150 years, steel production played a vital role in the shaping of our nation. This was especially true in Youngstown, Ohio, a part of what is now often referred to as âthe Rust Belt.â In their prime, however, the Youngstown mills ran along 25 miles of the Mahoning River and employed tens of thousands of people. All of that changed in September 1977 when the LTV Corporation announced that it was closing its Youngstown Works. Youngstown today struggles for its survival. Higginsâs photography places these decaying traces of the industrial landscape squarely amid the magnificence and magic of nature.
Two kinds of treatments were used in the current Book, namely, biological and chemical treatments, to reduce the concentration of four heavy metals (Al, Ni, Zn, and Pb) in the sludge collected from the electronic industry. A biological treatment called vermicomposting technique was employed to expose four different ratios of sludge (20, 50, 80, and 100%) mixed with goat manure and rice straw as a composting material to the earthworm species Eisenia fetida for four weeks. For the chemical technique, the sludge was washed with a mixture of two reagents (Na2 EDTA and Na2S2O5) at different volumes of washing solution (2.5, 5, and 7.5 mL to 1 g of sludge). The best reduction of heavy metals occurred in 7.5 mL with a percentage reduction of 5%, 12%, 16%, and 24% per gram sludge for Al, Ni, Zn, and Pb, respectively. Based on the findings, the vermicomposting technique shows greater potential over the chemical washing technique in reducing heavy metal concentration in electronic sludge.

This book presents an overview of the characterization of electronic waste. In addition, processing techniques for the recovery of metals, polymers and ceramics are described. This book serves as a source of information and as an educational technical reference for practicing scientists and engineers, as well as for students.
This book is about study of adsorption of heavy metals and dyes. Adsorption technique is well known for various applications, for which activated carbon is the popular answer. Activated carbon needs effective and economical alternative which we have given in this research. It includes synthesis of low cost adsorbents and its application to remove heavy metals and dyes from aqueous solutions. The adsorbents were prepared from various fruit shell wastes. The adsorbents were characterized with modern techniques to examine and confirm the adsorption. The study was extended by applying well known isotherm models and the rate of adsorption was determined with kinetic models. The nature of adsorption was investigated with thermodynamic study. The results were compared with reported adsorbents which concluded that these adsorbents had better adsorption capacity.

The book contains detection of heavy metals (as low as ppb level) using enzymatic inhibition technique. The toxicity of arsenic in drinking water is unexplainable and the different techniques including electrochemical procedure have been described here. The removal of arsenic was explained in packed bed and a mathematical model has been predicted here using adsorption isotherms. Finally, the model has been solved in visual basic and an extensive program was written in the following code. The instruments used and their techniques are vividly explained with specification and clear pictures. The references are also quite extensive in this publication.
