“…Cid et al [36] found a 43.3% of decrease in copper biosorption by esterifying biomass of the species Durvillaea antarctica using methanol in acid media. The presence of carboxyl, hydroxyl, sulfate, phosphate, and amine functional groups has been found to play a dominant role for the algae-metal interaction by an ion-exchange mechanism that occurs between heavy metals and intrinsic light metals ions such as Ca 2+ and Mg 2+ , and Na + and K + [37]. A summary of representative data for eiciency of copper removal for diferent types of algal biomass is presented ( Table 2).…”

Environmental metal pollution is a serious public problem, and it has become an issue leading to research in the eluent remediation area. Techniques involving biosorption processes have been found to be promising due to the low cost of nonliving biomaterials, which have the potential to adsorb metal ions from wastewaters. One of the most promising types of biomasses to be used as biosorbents is the seaweed biomass, particularly from brown algae. The biosorption capability of the seaweed biomass relies on their cell wall chemical composition, mainly composed of alginates and fucoidans, molecules with a high presence of functional groups that interact with metal ions. This book chapter focuses on the use of seaweed biomass for metal biosorption and the chemical basis underlying the process. The current state of the commercial status of biosorption technology based on seaweed biomass is presented. Examples of complementary uses of the algae biomass other than industrial wastewater cleaning processes are presented, and the potential reuse of the biomass after the biosorption focused on biofuel production is discussed.

“…Heavy metals released by a number of industrial processes are some of the major pollutants in soil and water resources [2]. Main industrial sources of pollution include electroplating, battery and mining industries discharging a variety of toxic metals such as lead, copper, nickel, zinc and cadmium [3,4]. Heavy metals are toxic and environmentally harmful substances; they have accumulating characteristics in nature as they cannot be degraded.…”

The widespread use of heavy metals in different manufacturing processes has resulted in their presence in the air, soil and aquatic ecosystems. Many manufacturing processes release their effluents into nearby streams and rivers due to non-availability of waste treatment technologies in the developing world. Industrialization has therefore been reported to be a major anthropogenic source of these elements and their compounds waterbodies. Conventional methods that are currently being used in the developed world (such as chemical precipitation, ultra-filtration, reverse osmosis, etc) are expensive and so, unaffordable to small-scale businesses prevalent in developing economies. The need for alternative, cheaper and available technologies therefore, cannot be over-emphasized. This study attempted to remove heavy metals (Cu 2+ and Cd 2+ ) from simulated and industrial (paint and textile) wastewaters using sugarcane biomass. A synthetic resin (Chelex) was used as control. Batch sorption experiments were conducted to assess the influence of contact time, adsorbent dose, adsorbate concentration, pH, agitation speed, temperature and particle size. Increases in the parameters (except particle size) gave corresponding increases in percentage adsorption of both metals. Optimal temperature for adsorption was achieved at 50 o C above which adsorption declined considerably. Experimental data for Cu 2+ and Cd 2+ fitted well into freundlich and langmuir isotherms. In textile effluent, 100% adsorption was achieved for both metals using sugarcane biomass in contrast to 89% and 91% for Cu 2+ and Cd 2+ respectively in chelex, a synthetic resin. Similarly, adsorption was 100% for both metals using the biosorbent. Sugarcane biomass may therefore be utilized for water and wastewater remediation in the developing world. Its biodegradability gives comparative advantage over alternative synthetic and expensive resins since its disposal will be more environmentally friendly.

“…Conventional methods for the removal of Cu from wastewater include reduction, ion exchange, evaporation, chemical precipitation and adsorption on activated carbon [4][5][6][7][8]. However, most of these methods have some disadvantages, such as toxic sludge generation and high operation costs when applied for low Cu concentration wastewater on a large scale.…”
