What else can I use apart from titration with expensive silver nitrate and mercury nitrate methods?
I have to test for chlorides in my effluent, I'm struggling to get silver nitrate solution so far. So I want to know an alternative way to know the concentration of Cl- in my effluent.
Dear Molefe
Thomas is right, ISE is another method. for chloride EPA 9212 method is used.
You can find the same at:

What do I need in terms of the lab equipment/apparatus, what do I need to buy? I will go through the link posted by Pravin I hope it has the apparatus and the method description.
Hi,
May be you can see here

Other techniques would be to run ion chromatography, AA, or ICP, but ISE would be easy. However, you may check if your ISE has interferences. With an ISE you would run various concentrations to determine the deflections.
If you might have nitrate or other ions, especially anions in the efluent,
the best method might be anions determination in the ion chromatography
method. And if you only wish to determine anions, you don't need to buy
the best there is on the market. Dionex Corp has been bought out by Thermo.
So please go ahead and contact your Thermo Corp. representative for
a low-price anion chromatograph instrument. Their friendly service
and sales representative will show you how to run standards and how to calibrate
and determine your Cl- ion contration even down to ppb level if you'd need.
Good luck to you.

Ion selective electrodes by Ion Meter as well as continuous monitoring selective electrodes of different companies are available in the market for chloride determination on site.
Ion Chromatography is the best method for most of the anions. Chloride ion
can be easily detected both qualitatively and quantitatively down to PPM
level. Please consult your nearby sales consultant of Diones Corporation--
Thermal analytical instruments Co., Ltd. Or go to a nearby University to
try your aqueous sample. In the year 1991 I sold 3 systems for Dionex IC
to South Korean Nuclear Power Corp that were able to detect ppb level of
chloride ions.
Mr. Wei
chloride in waste can be determined by very much recognized Mohr method. Digital chloride meter of selective electrode type available in market.
