An engineered biochar was fabricated via paper mill sludge pyrolysis under CO 2 atmosphere, and its adsorption capability for As(V) and Cd(II) in aqueous solution was evaluated in a batch mode. The characterization results revealed that the biochar had the structure of complex aggregates containing solid minerals (FeO, Fe 3 O 4 and CaCO 3) and graphitic carbon.
In this investigation, the concentrations of arsenic, cadmium, lead, manganese and zinc were determined in biological samples (blood, urine and scalp hair samples) of exposed paralysis and non-paralysed steel mill workers. For comparative purposes, unexposed healthy subjects of …

Cadmium compounds are poorly absorbed from the intestinal tract, but relatively well absorbed by inhalation. Skin absorption appears negligible. Once absorbed Cadmium has a very long half-life and is retained in the kidney and liver. It has been shown that cadmium is a poison entirely analogous to arsenic and mercury.

Cadmium is also found in meat, especially sweetmeats such as liver and kidney. In certain areas, cadmium concentrations are elevated in shellfish and mushrooms (Jarup 2002). Cadmium can also enter the food chain from water. In Japan, zinc mining operations contaminated the …
Cadmium intoxicants cause femoral and low back pain in initial manifestation, the further pain spread to the other areas of the body. Moreover, skeletal deformities can cause bone fractures . Renal damage in cadmium toxicity: Cadmium predominantly accumulates in kidney and liver, but it can be found in other tissues such as bone and placenta.
Need info on stripping CAD plating. I need to safely strip the CAD-plating from some parts. The parts are critical strength aircraft parts (so hydrogen embrittlement etc is a concern). Mechanical stripping is out due to tolerance/dimensional issues. Chemical stripping must be applied carefully because there is chrome plating on the same part ...

Cadmium can resist a humid atmosphere better than zinc, but it has a far less protecting power than zinc. The most common method of applying cadmium coating is by electroplating. Cadmium plating is done in cyanide baths containing a mixture of cadmium oxide and sodium cyanide to produce Na 2 Cd(CN) 4. The following is the formation:
Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817 ...
