2016, HydrometallurgyCitation Excerpt :However, it faces some deficiencies such as high solubility and lack of functionality in the presence of a chelating agent. On the other hand, sulfide precipitation of metals is a viable alternative (Mishra and Das, 1992). It provides high grade of heavy metal elimination over a wide pH range and possesses several advantages over hydroxide or carbonate precipitation, such as the low solubility and high stability of metal sulfides (Jandova et al., 2005).
Influence of sulfide concentration and macronutrients on the characteristics of metal precipitates relevant to metal recovery in bioreactors
2012, Bioresource TechnologyCitation Excerpt :The different metal depletion rate constants from the plots of Pb, Cd and Zn depletion for the different sulfide concentrations support the first-order kinetic model (Fig. 2). Several authors have found that the kinetics of the metal sulfide reactions is well described by a first order equation (Bryson and Bijsterveld, 1991; Lewis and Swartbooi, 2006; Mishra and Das, 1992). For Mn, Ni, Co and Zn, the authors showed a better data fit with a standard deviation close to 1, in contrast with the current study (Fig. 2) due to the presence of macronutrients that interfered with the metal sulfide precipitation process and caused competing precipitation reactions (Brezonik, 1994).
