Nickel generally provides good binding efficiency to His-tagged proteins but also tends to bind nonspecifically to endogenous proteins that contain histidine clusters. As stated above, a small amount of imidazole in the binding/wash buffer helps to control off-target binding.
All extractions are based on the aqueous solutions with the exception of nickel which is based on organic assay, (7 mg/L and 16 mg/L nickel in Stage 1 and 2 respectively). Cobalt was extracted preferentially over nickel, but two stages and only with a large excess of organic did the raffinate finally meet the required target for Ni:Co ratio.
Nickel and nickel compounds were considered by previous IARC Working Groups in 1972, 1975, 1979, 1982, 1987, and 1989 (IARC, 1973, 1976, 1979, 1982, 1987, 1990). Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consideration in the present evaluation.

Seawater contains approximately 0.5-2 ppb of nickel, and rivers contain approximately 0.3 ppb.Phytoplankton contains 1-10 ppm nickel (dry mass), resulting in a 10 3-10 4 bioconcentration factor compared to seawater. Bentic algae can be found both in freshwater and salt water, and may contain between 0.2 and 84 ppm nickel.

Subsequent chemical analyses of the plant tissues revealed foliar nickel concentrations varying from 7168 to 18,388 mg/kg on a dry weight basis.
Thoroughly wash produce grown in nickel-contaminated soil to remove any soil or dust. To reduce nickel particles in air from dust, cover bare soil with mulch and keep the soil moist, but not water-logged. If your soil nickel levels are high, consider not planting root vegetables, since nickel tends to stay in plant roots.
Furthermore, Terasvasara also said the HCT thickeners are proven to provide the best washing efficiency and reduce nickel loss in metal leaching residue. The deal is the latest Outotec has won for its 'Planet Positive' offering.
The Basamuk plant treats the concentrate to produce a mixed nickel-cobalt hydroxide product (MHP) which grades about 39% Ni and 3.8% Co. Washing Plant The first stage in treating the mined ore requires washing the feed material to remove coarse, barren rocks. The wash plant comprises four identical trains in parallel.
