Hexavalent chromium (Cr6+)is one of the chemical forms of chromium, which can be present in different  forms in the environment,especially it will dissolve in water in the form of CrO4 2-.  Hexavalent chromium  is very toxic, it may be a human carcinogen if ingested. Usually there are certain methods for Hexavalent Chromium removal, like: electrodialysis,precipitation,  active carbon adsorption, ion exchange etc. In which, ion exchange technology is considered as the more economic and highly efficient way for Cr6+ reduction.  Sunresin produce a type of premium grade polystyrene macroporous, weak base anion resin MA940  which is highly selective to Hexavalent chromium.The resin is with higher working capacity for adsorption  of Cr6+ from water and wastewater, like for Cr6+ removal from effluent in leather manufacturing, metal finishing,chromium plating etc. The Seplite MA940 is very tipical anion resin which is wi...

SEPLITE LSC750 is a weak acid, macroporous, chelating resin with amino phosphonic acid groups. This structure is good for the chelating with heavymetal ions. Compared with the chelating resin with amino carboxylic acid groups, resins with amino phosphonic acid groups are much easier to chelate with certain cation ions. SEPLITE LSC750  is more suitable for removing of the heavy metals like Ca2+,Mg2+,Sr2+,Ba2+,Ni+ etc  thus to fully purify the second brine during production of membrane caustic soda. For SEPLITE LSC750 resin,it enjoys the advantage of below: 1.Superior mechanical and excellent resistance to osmotic shock, good mechanical strength, 2.Low loss, lesstopping annually, stableKinetics performance 3.High chelating capacity,high chelating capacity leads to bigger amount of brine treated per cycle 4.More uniform for particle size,excellent running kinetics during regeneration Refer to Sunresin website for more information: http://en.sunresin.com/

Ion exchange resins for heavy metals removal from electroplating wastewater  Wastewater from metal finishing or electroplating industries contains high concentrations of metals contaminants, like Nicke, Zinc, Chrome, Cooper and etc, these heavy metals are hazardous to the environment and human, thus it can not be discharged directly to the nature.  Sunresin produces a series of chelating ion exchange resins, which are with very good performance for metals removal from electroplating wastewater.  The main types are for: Nickle removal, Chrome removal, Cooper removal. With their special structure and high selective to the metals in certain condition, the resins are with very good effect for adsorption of the metal ions. With high regeneration efficiency and strong bead strength, the resins are with long lifespan in operation.
