“…Many studies on the kinetics of nickel electrodeposition from an aqueous solution have been published [13]- [24].Most of these studies studied the kinetics based on charge-transfer controlled electrode kinetics [13], [14] or diffusionkinetic control associated with a typical nucleation process [15], [24 ]. A few studies were performed to study the kinetics of nickel removal under mass transfer contro [16], [17]. Djaenudin et al (2017) investigated the kinetics of nickel removal using a double chamber electrodeposition cell (DCEC).…”

Djaenudin et al (2017) investigated the kinetics of nickel removal using a double chamber electrodeposition cell (DCEC). They found that nickel ion removal in DCEC followed a first-order kinetic with a removal rate constant k = 0.12 h-1 (R2= 0.956).…”

The kinetics of nickel removal from aqueous solutions using a bio-electrochemical reactor with a packed bed rotating cylinder cathode was investigated. The effects of applied voltage, initial nickel concentration, the rotation speed of the cathode, and pH on the reaction rate constant (k) were studied. The results showed that the cathodic deposition occurred under mass transfer control for all values of the applied voltage used in this research. Accordingly, the relationship between concentration and time can be represented by a first-order equation. The rate constant was found to be dependent on the applied voltage, initial nickel concentration, pH, and rotation speed. It was increased as the applied voltage increased and decreased as the initial concentration increased. Its relation to the applied voltage can be fitted as follows: where ko =0.01695 min-1 and -β=0.431. pH and rotation speed have two dissimilar effects on the rate constant. Increasing the pH from 3-6 leads to an increase in the rate constant, while a decrease in the rate constant beyond pH=6 has occurred. Increasing the rotation from 100 to 300 rpm results in an increase in the rate constant. However, the rate constant decreases significantly beyond a rotation speed of 300 rpm.

“…Such biological materials can be microbial biomass, agricultural waste, industrial by-product or natural material, which has been heralded as a promising biotechnology for metal removal due to their high efficiency, low cost and large abundance (Gadd, 2009;Kurniawan et al, 2006a). For example, water hyacinth has been used as cell separator to reduce Ni concentration from 2200 g/L to 0.4 g/L in 72 h (Djaenudin et al, 2017). Different mechanism could be included in biosorption, such as absorption, ion exchange, complexation and precipitation (Figure 1-8).…”

Strategies for nickel and cobalt recovery from mine-impacted water using sulfate-reducing bacteria

With the increasing world demand and price of valuable metals such as nickel (Ni) and cobalt (Co), it has become more attractive to recover these metals from secondary streams such as mine-impacted water. Biogenic sulfide produced through a biological sulfate reduction process is a promising approach compared with the traditional hydroxide or chemical sulfide precipitation for metal recovery, as it can be produced on site and utilize the substances that already exist in the waste streams. Moreover, it is effective even with low metal concentrations and low pH solutions due to the low solubility products of the metal sulfides. However, the generation of fine particles in the sulfide precipitation process is a challenge and usually results in poor settling, which deteriorates the metal recovery efficiency. Despite this, the compositions of biogenic sulfide solutions from different sources are various depending on the electron donors and the influent characteristics, which may affect the metal precipitation reactions and particle settling properties. Therefore, the effect of using chemical sulfide and four biogenic sulfide-containing solutions for Ni and Co precipitation and settling was evaluated in this thesis. Results showed that phosphate was the main component enhancing particle settling whereas acetate and sulfate exhibited a smaller influence. The Ni and Co recovery were also assessed in a novel single-stage upflow fixed-bed sulfidogenic bioreactor treating metal and sulfate-containing wastewater (0-200 mg/L Ni and 0-10 mg/L Co). Over 99% of Ni and Co precipitated and settled in the bioreactor regardless of the initial metal concentration. Bacterial communities attached on the carrier materials and metal precipitates collected from the bioreactor bottom were also characterized. These findings helped describe the simultaneous treatment of sulfate-and metal-containing wastewater in a sulfidogenic bioreactor and provided information on how to scale up the reactor and to optimize the metal recovery efficiency. Ni and Co often co-exist in ores and the associated mine waste; however, their similar chemical behaviors have made the selective recovery of both metals a challenge. The addition of chemicals and energy in hydrometallurgy are common practices for Ni-Co concentrates that allows selective separation through precipitation, ion exchange and solvent extraction. Although these options are economically feasible for concentrates, the same technologies may not necessarily be attractive for secondary sources with lower, but still significant metal concentrations. Therefore, a new approach to separate Ni and Co using sulfate-reducing bacteria (SRB) based on the different microbial responses to metal stress was proposed in this thesis. Results show that Ni displayed higher solubility (52-99%) than Co (0.6-15.5%) in the presence of SRB and sulfide. This could be partially explained by the higher Ni stress to SRB that induced the production of extracellular proteins that can selectively complex Ni and stabilize it in th...
