Anhydrous zirconium sulfate is a colorless microcrystalline solid. Zirconium sulfate is also obtained as a white crystalline tetrahydrate, ZrSO4.4H2O. Both forms are soluble in water and noncombustible. It is corrosive to aluminum. It is used in chemical analysis, as an additive for lubricants, and for many other uses.

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

IDENTIFICATION AND USE: Zirconium disulfate forms white crystals. it is used in the preparation of nickel catalyst for the hydrogenation of vegetable oil; used for flame-resistant treatment of wool fabric; as a chemical reagent, in lubricants, and tanning of leather. Zirconium sulfate has been identified as being used in hydraulic fracturing as a crosslinker. HUMAN EXPOSURE AND TOXICITY: No human studies were found at time of review. ANIMAL STUDIES: Oral administration of zirconium (fed as 5 ppm zirconium sulfate) to rats from weaning until natural death failed to influence longevity, tumor incidence, or organ-to-body-weight ratios. Intracellular concentration sites of zirconium after injection of low doses of zirconium sulfate have been studied. Results show that zirconium is uniquely localized in the lysosomes of the lymph node macrophages where it is associated with phosphorus. At defined concentrations Zr(SO4)2 can both act as lymphocyte mitogens and augment the functional responsiveness of immune cells.

After exposing several hundred Long-Evans rats to drinking water containing 5 ppm zirconium sulfate for a lifetime, ... no analytical evidence /was found/ by a spectrophotometric method using chloranilic acid that zirconium was consistently absorbed from the gastrointestinal tract; indeed, the zirconium concentration in the male rat kidney was less than that of controls whose diet, like that of the treated, contained 2.66 ppm zirconium. The liver and the lung showed a slight increase of 0.7 and 1%, however, over that of controls, but the heart and spleen showed increases of 9.4 and 32%, with an average deposition in the five tissues of 9.9%. Females, with an average tissue distribution of only 2.6%, showed the striking difference of 2.4% less zirconium in the spleen than in the controls.

Method 4500-Sulfate ion E. Turbidimetric Method for the determination of sulfate ion in water and wastewater. Sulfate ion is precipitated in an acetic acid medium with barium chloride so as to form barium sulfate crystals of uniform size. Light absorbance of barium sulfate suspension is measured by a photometer at 420 nm and the sulfate ion concentration is determined by comparison of the reading with a standard curve. This method is applicable in the range of 1 to 40 mg sulfate ion/1. The minimum detectable concentration is 1 mg SO4/l. Interferences /include/ suspended matter in large amounts, silica in excess of 500 mg/l and large quantities of organic material. With a turbidimeter, in a single laboratory with a sample having a mean of 7.45 mg sulfate ion/l, a standard deviation of 0.13 mg/l and a coefficient of variation of 1.7% were obtained. Two samples dosed with sulfate gave recoveries of 85 and 91%. /Sulfate/|Method 4500-sulfate ion F. Automated Methylthymol Blue Method for the determination of sulfate ions in water and wastewater. Barium sulfate is formed by the reaction of the sulfate ion with barium chloride at a low pH. At high pH, excess barium reacts with methylthymol blue to produce a blue chelate. The uncomplexed methylthymol blue is gray. The amount of gray uncomplexed methylthymol blue indicates the concentration of sulfate ion. To remove interferences from cations, an ion-exchange column is used. This method is applicable over a range of 10 to 300 mg sulfate ion/l. In a single laboratory a sample with an average concentration of about 28 mg sulfate/l had a standard deviation of 0.68 mg/l and a coefficient of variation of 2.4%. In two samples with added sulfate, recoveries were 91% and 100%. /Sulfate/
