Titration of Chemetall Americas non-Chromated Deoxidizers (ferric iron concentration)

A test kit is available for this titration procedure (see below) or supplies can be ordered individually

Complete Test Kit Part Number: OKT9605-85 (or 45218520)

Solution-Item	Item	Amount	Part Number	BASF Number
Gardotest Indicator 195	10% Sulfosalicylic Acid	60 mL	OKT-9646-H	50562418
Gardotest Solution 90	0.10 M Disodium EDTA	250 mL	OKT-9656-K	50560654
Sample bottle	Glass	120 mL	OKT-9688	45218459
Pipettete, Full Calibration	0 – 5.0 mL	1	OKT-9677	45218454

Refer to the product specific technical information sheet for the appropriate sample size and multiplying factor F or ask your technical sales representative

Procedure

1.    Fill the 120 mL sample bottle about half full with tap water. Next, using the 5 mL dropper, measure out appropriate sample volume of the product and add this to the water in the bottle. 2.     Add 30 to 40 drops (1.5-2.0 mL) of Gardotest Indicator 195 to the bottle. Swirl to mix. The color will turn dark reddish purple. 3.    Fill the 5 ml. pipette exactly to the zero mark with Gardotest Solution 90, and add this to the mixture in the bottle, a few drops at a time with swirling between additions, until the red color changes to yellow.

4.   Record the number of mL used. Call this Titration T. This completes the analysis. 5.   If the calculation is required, use the equation below to calculate concentration. If no calculation required, report mL of titrant used. CALCULATION  TF  =  vol % (or oz/gal) of respective BASF Chemetall Americas product. T is the number of milliliters used of the titrant to reach the end or equivalence point. F is the multiplying factor found in the technical data sheet for the respective product being analyzed. For Deoxidizer LNC, the factor for iron is actually 1.1
