%" Pr Pro! o!es ess s In2or In2orma mati tion on Adhemax® Adhemax ® Neutralizer Cr is is based on a hydroxylamine com#ound. Adhemax® Adhemax ® Neutralizer Cr #rotects the subse"uent #rocess ste#s 8 es#ecially the Adhemax® Adhemax ® A!ti3ator '4 and '4 and Adhemax® Adhemax® A!ti3ator NA NA - from drag-in of hexavalent chromium and sulfite and therefore increases their stability and lifetime. ,om#ared to other reducing agents9 the drag-in of Adhemax® Adhemax ® Neutralizer Cr into the Adhemax® Adhemax ® A!ti3ator '4 and '4 and Adhemax® Adhemax ® A!ti3ator NA is NA is less critical.

5.1 ml #reci#itation agent 'edi/anth C is C is added to 155 ml of rinse 0ater sam#le at a #@ of ( - 159 being continuously stirred. After a reaction reaction time <0hile the solution is stirred= of * min.9 the solution solution to be treated treated has to be clear and colorless. )hen another 5.1 ml #reci#itation agent 'edi/anth C is C is added no further clouding should a##ear.

he resulting ml of #reci#itation agent 'edi/anth C for C for 155 ml rinse 0ater sam#le gives the amount of #reci#itation agent in liter for 155 l rinse 0ater to be treated.
