What does the negative sign mean in Langmuir's isotherm?
hello, could you help me, please. I need to do a regression with the breakthrough curve data, but I don't know how to do it. I don't know how to solve the differential equations involved in the development of the curve.

This means that one should be careful when using various graphical methods, here an analogue of L-B plot. Here, presumably, the equilibrium curve is convex, but it should be concave. This could be the result of unidentified side effects e.g. adsorbent particle aggregation, pore blocking, poisoning etc.

I have got similar results when plotting Ce/qe vrs Ce I got the intercept negative y = 4.8994x - 11.412 and R2 = 0.9947. Does it mean results of the experiments are not valid??

The results may be explained as follows:The negative value of Langmuir constant (b) for Pb(II) suggest that it gives RL value more than 1 and adsorption of Pb(II) on synthesized resins were very difficult. It may be due to, As ionic radius increases, charge density decreases, the adsorption capacity of synthesized resins decrease as for Pb(II).

Hi Sami Abdullatif, I also have same result like you... y = 4.573x - 7.546, y = 0.479x - 0.031 and y = 0.513x - 0.020 and regression value is 0.999. so, I think your explanation is helpful.

I obtain the equation y=-0.2234x + 4.0833
R²=0.3511, what does the negative value is slope means
