Apakah Maksud Zeta potential analysis techniques?

Zeta potential analysis techniques adalah kaedah untuk mengukur dan menganalisis potensial zeta suatu zarah dalam sistem disperse. Potensial zeta merujuk kepada beban elektrostatik pada permukaan zarah yang boleh menentukan sifat-sifat pepejal cecair atau cecair cecair dalam sistem disperse. Dengan menggunakan teknik analisis zeta potential, penyelidik boleh memahami interaksi antara zarah-zarah dan media disperse serta memprediksi kesan perubahan kestabilan sistem.

Dalam analisis zeta potential, terdapat beberapa teknik yang digunakan untuk mendapatkan nilai potensial zeta. Antara teknik yang biasa digunakan termasuklah:

  • Elektroforesis laser Doppler: Kaedah ini mengukur halaju partikel yang bergerak dalam medan elektroforesis untuk mengira potensial zeta.
  • Pulsa-bayaran analisis: Teknik ini menggunakan pengukuran ketumpatan partikel selepas dikenakan kepada medan elektrik untuk mengira potensial zeta.
  • Analisis mikroaliran elektrokinetik: Teknik ini memanfaatkan pengukuran aliran kecil zarah dalam cecarian elektrolit untuk mengira potensial zeta.

Nilai zeta potential yang diperoleh dari analisis ini dapat memberikan maklumat yang berguna bagi pelbagai aplikasi dalam bidang kimia, farmasi, dan kejuruteraan. Dengan pemahaman yang lebih mendalam tentang sifat elektrokinetik partikel dalam sistem disperse, penyelidik dan industri boleh meningkatkan kecekapan proses pengeluaran, penjanaan tenaga, dan pembuatan produk.

Zeta potential is the electrical potential at the slipping plane. This plane is the interface which separates mobile fluid from fluid that remains attached to the surface.
Zeta potential is a scientific term for electrokinetic potential in colloidal dispersions. In the colloidal chemistry literature, it is usually denoted using the Greek letter zeta (ζ), hence ζ-potential. The usual units are volts (V) or, more commonly, millivolts (mV).  From a theoretical viewpoint, the zeta potential is the electric potential in the interfacial double layer (DL) at the location of the slipping plane relative to a point in the bulk fluid away from the interface. In other words, zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle.
The zeta potential is caused by the net electrical charge contained within the region bounded by the slipping plane, and also depends on the location of that plane. Thus, it is widely used for quantification of the magnitude of the charge. However, zeta potential is not equal to the Stern potential or electric surface potential in the double layer, because these are defined at different locations. Such assumptions of equality should be applied with caution. Nevertheless, zeta potential is often the only available path for characterization of double-layer properties.
The zeta potential is an important and readily measurable indicator of the stability of colloidal dispersions. The magnitude of the zeta potential indicates the degree of electrostatic repulsion between adjacent, similarly charged particles in a dispersion. For molecules and particles that are small enough, a high zeta potential will confer stability, i.e., the solution or dispersion will resist aggregation. When the potential is small, attractive forces may exceed this repulsion and the dispersion may break and flocculate. So, colloids with high zeta potential (negative or positive) are electrically stabilized while colloids with low zeta potentials tend to coagulate or flocculate as outlined in the table.

Zeta potential can also be used for the pKa estimation of complex polymers that is otherwise difficult to measure accurately using conventional methods. This can help studying the ionisation behaviour of various synthetic and natural polymers under various conditions and can help in establishing standardised dissolution-pH thresholds for pH responsive polymers.
