摘要： The invention pertains to a method for reduction of the cyanide content of a metals-containing wastewater fraction by contacting a wastewater fraction comprising cyanide compounds and metal compounds, with a metals content of at least 100 ppm, with hydrogen peroxide and a solid catalyst comprising at least 50 wt.% of a copper salt with a solubility of less than 10 exp(-5) mol/liter (in water at 20°C, 1 atm).
It has been found that when a solid catalyst comprising at least 50 wt.% of a copper salt with a solubility of less than 10 exp(-5) mol/liter (in water at 20°C, 1 atm) is used in combination with hydrogen peroxide in the reduction of the cyanide content of a cyanide compound-containing wastewater fraction having a metal compound content of at least 100 ppm, a method is obtained which shows an efficient removal of cyanide compounds from a difficult to treat fraction.
摘要翻译：本发明涉及通过使包含氰化物化合物和金属化合物的金属含量至少为100ppm的废水部分与过氧化氢和固体催化剂接触来降低含金属废水部分的氰化物含量的方法，所述固体催化剂包括至少50重量％的溶解度小于10埃（-5）摩尔/升的铜盐（在20℃的水中，1个大气压）。已经发现，当组合使用包含至少50重量％的溶解度小于10埃（-5）摩尔/升（在20℃的水中，1个大气压）的铜盐的固体催化剂时与过氧化氢相比，含有金属化合物含量至少为100ppm的含氰化合物的废水馏分的氰化物含量降低，得到了从难处理馏分中有效除去氰化物的方法。

摘要： A composite material comprising 10-98 wt.% of a bio-based particulate or fibrous filler and at least 2 wt.% of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid.
Preferably, the filler is in the form of particles, fibers, and/or random or non-random layers. A plant-based filler may be used, in particular a cellulosic or lignocellulosic material, more in particular one or more materials selected from wood chips, wood flakes, sawdust, pulp, e.g., pulp of (recycled) paper or other fiber pulp, and plant-derived fibers such as cotton, linen, flax, and hemp. An animal-derived filler, in particular an animal-derived fiber such as wool, hair, silk, or feathers may also be used.
