Abstract
The growing need for development of new methods in chemical technology represents a major challenge facing mineral, metallurgical and material processing industries in the recent years. Water pollution is nowadays a matter of deep apprehension and as far as the toxic metals and the toxic dyes are concerned, it is known that elevated concentrations of them are detrimental for aquatic life and through the food chain, are toxic for mankind. Therefore, intense scientific research is being directed towards the implementation of novel approaches dealing with the efficient removal of toxic metals and toxic dyes from wastewaters. Sorption and flotation are considered as important treatment technologies for this problem and several novel sorbents and processes continuously appear in the scientific literature. Accordingly, this work is devoted to study the different factors controlling the separation of BG dye, Cu2+ ion and Pb2+ ion (used in this work) from different aqueous media. Sorption and flotation techniques were the best among the well known separation methods because of their simplicity, saving time, accuracy alongside their inexpensive chemicals and equipment. Moreover, this investigation aims to establish the use of cheap and widely spread sugar beet pulp and the preparation of some modified forms (ASBP, BSBP) as sorbents and oleic acid as surfactant in a process known as sorptive-flotation.
