Paint pigments inorganic

AppHcations of mercury include use in batteries (qv), chlorine and caustic soda manufacture (see Alkali and chlorine products), pigments (see Pigments, inorganic), light switches, electric lighting, thermostats, dental repair (see Dental materials), and preservative formulations for paints (qv) (1—3). As of the end of the twentieth century, however, increased awareness of and concern for mercury toxicity has resulted in both voluntary and regulatory reduction of mercury usage (see also Mercury compounds). 

Paints. Paints account for perhaps 3% of sulfur consumption (see Paint). The main sulfur use is for the production of titanium dioxide pigment by the sulfate process. Sulfuric acid reacts with ilmenite or titanium slag and the sulfur remains as a ferrous sulfate waste product. Difficulties with this process have led to the development of the chloride process (see Pigments, inorganic Titanium compounds). 

The procedure of determination of metals in the thin layer without elimination of the non-volatile organic components for different paints containing inorganic pigments was developed. Several techniques of sampling from paint-and-lacquer materials for X-ray fluorescence analysis were proposed. For the study of nonhomogenity of metal distribution in the thin layer we used additionally the local method of X-ray fluorescence analysis.

The separated pigment (extender) is usually used as starting material for analysis (see Section 10.1.1). If quantitative separation is not possible (e.g., in emulsion paints) the inorganic pigment (extender) fraction can be obtained by ashing the nonvolatile fraction for further details see [10.5]. 

Emission spectroscopic methods, due to their high intrinsic sensitivities, are techniques of choice much sought after in forensic science. Fluorimetry has been applied to the analysis of mineral oils, grease, inks, and drugs (e.g., LSD), whereas X-ray fluorescence has found extensive applications in the analysis of inorganic materials (e.g., paint pigments and glass).
