Introduction

This library allows C programs to search and query pHtools buffer databases as well as compute acid/base buffer properties of mixtures. The kinds of operations supported include:

create complex aqueous acid/base solutions
mixing solutions
predicting buffer properties
- pH
- ionic strength
- titrations (Cb)
- buffer capacity
- time derivatives of above quantities

Algorithms

The algorithms follow closely those of Dougherty et al. 2006.

D. P. Dougherty, E. R. D. C. Neta, R. F. McFeeters, S. R. Lubkin, F. Breidt Jr. 2006. Semi-mechanistic partial buffer approach to modeling pH, the buffer properties, and the distribution of ionic species in complex solutions. Journal of Agricultural and Food Chemistry. 54(16):6021-6029

Installation

Download and unpack the source
cd libpHtools/src
make libpHtools
Copy resulting shared library.so.#.#.# to where you want it (e.g. /usr/lib64)
(Optional) Copy header files from /src to your system's default location (e.g. /usr/include/libpHtools/)

Developers wishing to write programs that use libpHtools should install both the shared library and the header files.

Availability

Current availability is by source code alone. This section will be updated as more offerings are provided by the libpHtools development team.
