The aim of this book is to introduce to the principles and applications of a branch of chemistry called surface and colloid chemistry. Most science students are taught physicochemical principles pertaining to gases, liquids, and solids. The matter around us is recognized to be made of these three states of matter. However, in uni- versity chemistry textbooks, seldom more than a chapter is devoted to the science of surface and colloid chemistry. At technical schools worldwide, the same is the case, in general. However, in the realm of applications of physico-chemical technology. the science of surface and colloid chemistry is one of the most important. Ushbu kitobning maqsadi kimyoning sirt va kolloid kimyo deb ataladigan bo'limining tamoyillari va qo'llanilishi bilan tanishtirishdir. Ko'pgina fan talabalariga gazlar, suyuqliklar va qattiq moddalarga tegishli fizik-kimyoviy tamoyillar o'rgatiladi. Atrofimizdagi materiya materiyaning ushbu uchta holatidan iborat ekanligi e'tirof etiladi. Biroq, universitetlar kimyo darsliklarida sirt va kolloid kimyo faniga bir bobdan ko'proq ajratilgan. Dunyo bo'ylab texnik maktablarda, umuman olganda, xuddi shunday. Biroq, fizik-kimyoviy texnologiyani qo'llash sohasida. sirt va kolloid kimyosi fani eng muhim fanlardan biridir
