By measuring IR for a series of prepared dilutions, a calibration curve can be created for a particular chemical, and the line’s equation calculated.The unknown concentration of other dilutions of that same chemical can be determined by measuring the sample’s IR and solving for concentration in that line’s equation: are constants for that line).

It is a prerequisite for human health and well-being” (“Water for Life”).

Yet 11% of the world’s population does not have access to safe drinking water (“Millennium Development Goal”).

The solute is the substance being removed, and the adsorbent is the solid material used for the process (Armenante).

There are two methods: filtering water through adsorption columns, or batch adsorption, which is a mixing process (“Adsorption/Active Carbon”; Bungay).

Many things can contaminate water sources, but this project focused on herbicides, fertilizers, and fungicides, which enter surface water from urban and agricultural runoff and percolate into groundwater from farm irrigation and urban lawn watering (“Managing Stormwater Runoff”).

Contaminants are documented at levels above accepted guidelines for safe drinking water (“Agricultural Chemicals”; “Understudied Fungicides”; “Study Confirms Glyphosate”; Biello), and may be carcinogenic or cause other problems for body systems (“Drinking Water Contaminants”).

(K-Patents, 2011) IR was used in this project to measure the concentrations of chemical contaminants in water.

The solution’s concentration can be measured using an Abbe refractometer.

Public water treatment disinfects and removes sediments and harmful chemicals.

Filtration, one step in water treatment, uses activated carbon to remove chemicals from water by binding and removing them, a process called adsorption.
