    Chromium (Cr) plating using trivalent chromium has been investigated as a replacement for the highly-toxic hexavalent chromium bath. Herein, we report novel chromium plating baths using hydrate-melts. Hydrate-melts have been investigated in recent years as an electrolyte for aqueous Li-ion batteries with a wide electrochemical window, and can be used as an electroplating bath in which the reduction of protons, i.e., bath decomposition, is suppressed. By using a hydrate-melt for electroplating with trivalent chromium, the increase of local pH during electrolysis is suppressed and generation of the electrochemically-inert oligomer of chromium hydroxide can be avoided. Crystalline chromium electrodeposits were successfully obtained from the hydrate-melt-based aqueous baths, which had not been possible with the conventional trivalent chromium process requiring organic coordination agents. Moreover, a current efficiency greater than 80% was achieved. The hydrate-melt-based aqueous bath, with low material cost, is a promising candidate for industrial trivalent chromium plating.

    <p>The mechanism of nodulation in copper electrorefining process was investigated by experimental method and simulation, in particular as for its growth in height. Due to the high current density at the tip, the nodule height increased as an exponential function of the time for electrolysis. Therefore, the growth behavior of nodules was strongly affected by the size of the nucleus and the existence of the threshold size to lead an electrical short circuit was suggested. Since some nodules obtained in the industrial process included mold releasing agent carried from anode-casting process, mold releasing agents are considered to be one of the main causes of the large nodule and need to be removed for the improvement in the current efficiency.</p>

    Abstract The immobilization of arsenic in the form of scorodite (FeAsO4·2H2O), which has excellent chemical stability, is attracting attention as a method for treating wastewater containing high concentrations of arsenic generated at nonferrous metal smelting plants. Scorodite, with its low solubility and high arsenic content per volume, is expected to be an environmentally friendly arsenic fixation method suitable for final disposal. Various scorodite synthesis methods have been studied. The first synthesis method proposed is the hydrothermal method using an autoclave to synthesize highly crystalline scorodite. Although the hydrothermal method is capable of synthesizing scorodite with good crystallinity, from an economic point of view, scorodite synthesis under ambient pressure and at low temperatures is more attractive. As a low-temperature scorodite synthesis method under atmospheric pressure, the oxidation of Fe(II) process by O2 bubbling was proposed. In this method, ferrous sulfate is added to an arsenic-containing solution as a Fe ion source, and in situ oxidation of Fe(II) by O2 or air bubbling to form scorodite with good crystallinity. In addition to temperature, other conditions, pH, Fe/As ratio, and reaction time have been reported to affect scorodite crystallization. Recently, scorodite synthesis using solid iron oxide as the Fe source for scorodite synthesis, instead of aqueous Fe salt solutions, has attracted much attention. In this presentation, we will report on the investigation of reaction parameters, such as the type of iron oxide and reaction temperature, for the scorodite synthesis using solid iron oxide.

    More details Close

    The anodic dissolution behavior of chromium metal in concentrated aqueous chloride baths was investigated. We worked on the development of an electrolyte that suppresses passivation of the electrode and enables highly efficient anodic dissolution, and combined it with chromium electrodeposition at the cathode as a counter reaction, we aimed to construct an advanced new electrodeposition process using concentrated aqueous solutions. It was confirmed that anodic dissolution is possible in concentrated chloride baths due to the destabilization of the surface film. The valence of the dissolved ions is considered to be divalent and trivalent. Chromium metal is electrochemically inert in ordinary dilute aqueous solutions, but it can be used as a soluble anode in concentrated chloride baths.
