Graph of Figure 3 shows the relationship between log (x/m) and C Isotherm and Freundlich equation log according to figure 4 shows the sap House between C/(x/m) and C equation for Langmuir Isotherm based on Pb uptake of fosof acid to soak the rice husk charcoal kamman foe concentrated on 30% 700°C

Chart 3 shows the relationship between log (x / m) and log C-based equation, Freundlich Isotherm and Figure 4 show the Sapta relationship between C / (x / m) and C-based equation, Langmuir Isotherm to absorb lead. of activated charcoal husk soaked acid phosphoric acid at 30% concentration stimulated burn at temperatures 700 ° C.

Curve shows the relationship between the 3 log (x / M) and log C according to equation Freundlich Isotherm and Figure 4 the SAPTA relationship between. C / (x / M) and C according to equation Langmuir Isotherm in adsorption of lead of activated carbon rice husk in concentrated phosphoric acid 30%.700 ° C.
