Ion content in the sample (weight %)

Calculate the weight fraction of each individual ion in the sample (w%), based on ion concentration (ppm or mg/L), volume of water (mL), and the dry mass of the sample (g).

Usage

fun_salt_wt(salt_ppm, dry_g, water_ml)

Arguments

salt_ppm

Ion concentration in ppm or mg/L

dry_g

Dry sample mass in grams

water_ml

Volume of water in millilitres

Value

Numeric value for ion content in the sample expressed as weight percentage (w%)

Details

Eqn 1. Weight fraction (w_i), as preparation for charge balance equations.

The calculation is: $$ w_i = \frac{C_{\mathrm{ppm}} \times V_{\mathrm{water}}}{10000 \times m_{\mathrm{dry}}} $$ where:

• \(C_{\mathrm{ppm}}\): ion concentration in ppm or mg/L

• \(V_{\mathrm{water}}\): volume of water in millilitres

• \(m_{\mathrm{dry}}\): dry mass of the sample in grams
