Phosphorus Speciation in Sludge from Nickel Electroplating

The recycling of secondary resources to close material cycle loops should reduce the consumption of natural resources and thus help to reduce the environmental impact. For recycling, it is crucial to consider not only the nickel (Ni) content in the secondary resources, such as Ni plating waste liquids and sludge, but also the impurity levels, particularly the phosphorus (P) concentration. This study characterized the P species in three sludges from Ni electroplating processes using P K-edge X-ray absorption near-edge structure (XANES) spectroscopy. The Ni and P concentrations in the sludges ranged from 11 to 41% and 2,800 to 24,000 ppm, respectively, depending on the type of sludge. The P K-edge XANES analysis identi ed phosphates and organic P as the major P species in the sludges, and hypophosphite and phosphite species as minor species. These ndings provide detailed knowledge that should help to control P in Ni electroplating sludge.

“…Originally, all trade data come from the customs statistics of countries or territories. The aluminum, copper, and iron trade analyzed in this study refers to the trade of three metals measured in physical Besides the abovementioned publications, there have been quite a few other cases of material trade flow analysis applying either the physical method [24][25][26][27][28][29] or the monetary method [30][31][32], and some of these studies even analyze the global supply chain or network of materials among countries and territories. The salient findings of these studies are reasonable, such as that at the final goods level, Japan is a net exporter of iron and aluminum embedded in final products because it has been a provider of automobiles and many other manufactured products to the world [21].…”

“…Compared to the physical method, the monetary method has at least two advantages: (1) it enables researchers to infer material concentrations for all concerned final products just by using the IO-based WIO-MFA model, therefore avoiding spending a lot of time collecting data on metal concentrations; (2) unlike trade data in physical units that sometimes are not recorded in the customs statistics, trade data in monetary units always exist; especially for the United States and Japan, these monetary trade data are already well compiled in their IO table with ≈400 sectors [22,23], thus can be directly used and will help save a great deal of time. Besides the abovementioned publications, there have been quite a few other cases of material trade flow analysis applying either the physical method [24][25][26][27][28][29] or the monetary method [30][31][32], and some of these studies even analyze the global supply chain or network of materials among countries and territories.

The hidden trade of a material (e.g., aluminum) refers to the trade of that material embedded in final products (e.g., automobiles). There are two methods for estimating the hidden trade amount of materials: (1) the physical method relies on the physical trade data (measured by physical units) in which products are categorized according to the standard international trade classification codes or the harmonized system codes; and (2) the monetary method relies on the monetary trade data (measured by monetary units) in which products are categorized in accordance to the sectors of an input–output (IO) table. Information on material concentrations in products can be relatively quickly estimated by an IO-based model in the monetary method, but will have to be collected from various sources with intensive time cost in the physical method. Exemplified by the U.S. hidden trade of aluminum, iron, and copper in 2007, this study attempts to compare the two methods. We find that, despite the unavoidable but reasonable differences in the amounts of three metals trade, the results generated by the two methods are consistent with each other pretty well for final products at the level of end-use product groups (e.g., total transportation facilities). However, the comparison for specific products (e.g., automobiles) is challenging or does not generate consistent enough results. We suggest that similar estimations be done for more materials, more countries/territories, and different years, to gain experience, reduce estimation time and costs, and increase the knowledge base on metal flows in society.

“…Materials that contain nickel are becoming increasingly useful from the standpoint of physical and other properties; however, the demand for nickel has grown rapidly as with other metal resources, and there have been reports of global environmental problems accompanying its extraction and refining [6]. In addition to past reports of impacts including loss of animal and plant habitat accompanying extraction and refining [7] and on biodiversity [8], there have been case reports from nickel ore-and ferronickel/nickel metal-producing countries of encroachment on nature protection zones [9]; inappropriate environmental management at production facilities accompanied by heavy metal pollution [10,11]; and emissions including sulfur oxides and mining waste [12].…”
