chromium process plant in india

Most of the tanneries in India adopt the chromium tanning process because of its processing speed, low costs, and light color of leather and greater stability of the resulting leather. In the chromium tanning process, the leather takes up only 60–80% of applied chromium, and the rest is usually discharged into the sewage system causing .

Chromium in Agricultural Soils and Crops: A Review

2017-4-22  Chromium is the 7th most abundant element in the Earth and the 21st on the Earth’s crust (0.1–0.3 mg kg −1) (Katz and Salem 1994).The most stable forms of this metal in the environment and in biological systems are the trivalent Cr(III) and hexavalent Cr(VI) (Becquer et al. 2003).Other intermediate valence states of Cr exist in nature, but they are generally unstable.

Chromium toxicity in plants ScienceDirect

2005-7-1  Chromium is found in all phases of the environment, including air, water and soil ().Naturally occurring in soil, Cr ranges from 10 to 50 mg·kg −1 depending on the parental material. In ultramafic soils (serpentine), it can reach up to 125 g·kg −1 (Adriano, 1986).In fresh water, Cr concentrations generally range from 0.1 to 117 μg L −1, whereas values for seawater range from 0.2 to 50

Reduction Monitoring in the Chromium Wastewater

Wastewater from electroplating facilities and certain types of chemical plants contains toxic forms of hexavalent chromium such as chromate and dichromate. The hexavalent chromium in this wastewater must be reduced before the water can be discharged. This requires a two-step process: hexavalent chromium (CR6) is reduced to trivalent chromium (CR3); and CR3 is precipitated as chromium
