Copper-nickel chelate heavy metal treatment agents in addition to copper agent

[Products] copper-nickel chelating agent is a strong chelating heavy metal ions chemical agents. The synthetic process of the graft, branched chelating group to chelate heavy metals by forming a stable insoluble precipitate. The reaction not only in the room temperature and a very wide range of pH value conditions, and without heavy metal ion concentration. Even if the treatment of wastewater containing complex composition, but also a variety of heavy metal ions can better precipitation wastewater, wastewater to meet emission standards. Mechanism of action of the product through a variety of chelating groups chelation of heavy metal ions, resulting in a hydrophobic structure and precipitation; same time, the body structure of the polymer under by flocculation and netting effect significantly improve the sedimentation rate and removal, to get rid of the shortcomings of the linear chelate precipitate. Features floc thick, precipitation, dehydration is fast, easy post-processing, less sludge and stable non-toxic, no secondary pollution. [Performance] Item Standard Appearance brown or reddish-brown liquid density (g/cm3, 20 ° C) ≥ 1.05 Water insolubles (%) ≤ 0.5 pH value (1% water solution) 9.0-12.5 chelating capacity (mmolCu / g) ≥ 1.0 [use] [dosage] dosage of about wastewater 0.05-1/1000. The specific amount based on the concentration of heavy metals in the on-site wastewater; formulated can be formulated into a solution of 5% -20% Stir well, add water, pay attention to use free of heavy metals diluted with water; [Condition] for wastewater pH range 4-12, alkaline better; [chelation of various metal ions was in the order] Hg 2 +> Ag +> Cu2 +> Pb2 +> Cd2 +> Zn2 +> Ni2 + Cr3 +> Fe2 +> Mn2 +. [Use of] applies to mining and metallurgy, machinery manufacturing, chemical industry, electronics, instrumentation and other industrial processes in the discharge of waste water containing heavy metals. [Precautions] 1, first with a pH in the powder to adjust the pH value of wastewater, and adjust the content of heavy metal ions in the effluent pH value is detected, according to the concentration of heavy metal ions in wastewater calculate the required amount of MCP-1, added in accordance with the amount of MCP solution. 2, the product is diluted the general dilution ratio can be controlled in the range of 5% to 15%, please use tap water for dilution or other excluding heavy metal ions in water, do not use groundwater. 3, the medicine diluted Proposed dosing and to the conservation of the products to reduce processing costs. Chelating sedimentation process after dosing inorganic or organic flocculants to improve the treatment effect. 4, the agents, strongly alkaline liquid, do not direct contact with skin contact, rinse with plenty of water. Packaging and storage] 25kg / barrel, chemical drums stored in a cool, dry, well-ventilated place. Appendix 1 small test method) to a certain amount of heavy metal wastewater 2) adjust the PH and pink water PH value to about 10 to detect the concentration of heavy metal ions in water samples, according to the detected concentration of heavy metal ions, to determine the added amount of the heavy metal chelating agent, MCP-1. 3) adding a heavy metal chelating agent MCP-1, sufficient mixing. 2, scene 1) heavy metal chelating agent MCP-1 directly added to the transient response with heavy metal ions from wastewater, the best way is stirring once every 10min; 2) the concentration of the uncertain heavy metals in the waste water, the experiment chamber experiments to determine the amount was added. 3) containing heavy metal ions from wastewater treatment for the different concentrations of the heavy metal chelating agent is added in an amount of MCP-1 by the ORP to automatic control. 3, the heavy metal ions per gram of the heavy metal chelating agent MCP-1 can handle the amount of metal ions Cu2 +, Ni2 + Pb2 + Zn2 + and Cd2 + Cr3 + Sn2 + Mn 2 + treatment (mg / g) 134.85 129.20 440 144.30 241.54 76.11 258.40 120.78
